Electric Vehicles: The Inevitable Future of Transportation

Image by OpenAI

Legacy automakers want the US Congress to stop California's plan to greatly restrict the sale of gas-only cars by 2035. Eleven other states follow California's emission plan, including New York, Massachusetts, and Oregon. Together, these 12 states account for approximately 40% of the US new vehicle market.

In May, the US House of Representatives voted to cancel the special Environmental Protection Agency (EPA) permission given to California by all previous administrations (Republican or Democrat). Without this permission, vehicles in these states would only be required to follow the (much more relaxed) federal emissions standards. On June 12th, President Donald Trump signed the resolutions that revoked the EPA waiver for three California vehicle emissions rules. 

Hours later, California's Governor said the state would sue for the right to regulate its own air quality and would double down on its efforts to transition away from fossil fuels. The Governor went on to say this move by Congress and the Trump administration will “Make America Smoggy Again.”

The Alliance for Automotive Innovation, representing companies like GM, Toyota, and Volkswagen, claims that complying with the California mandate will cause financial hardship for the automakers. They said that to comply with the rule, automakers will have to reduce the total number of cars they sell to inflate the share of EVs. They don't seem to understand that increasing EV sales is the better option. This is especially ironic that this "innovation" alliance is arguing for the status quo to continue even into 2035. Perhaps they should consider renaming themselves The Alliance of Luddite Automakers.

EVs are poised to dominate the future of personal transportation, driven by declining battery costs, technological advancements, environmental imperatives, and shifting consumer preferences. Charging infrastructure is expanding rapidly, with over 170,000 public chargers in the US as of 2025. Battery costs have dropped over 80% since 2010. This has improved EV range while making them more affordable (and more profitable). By 2035, battery costs will (again) decline significantly, and EVs will be more profitable than gas-powered vehicles. 

EVs offer superior performance, lower maintenance costs, and zero tailpipe emissions, aligning with global efforts to combat climate change. Governments worldwide are setting ambitious targets, with the EU aiming for all new cars to be zero-emission by 2035. Consumer demand is surging, as evidenced by EVs accounting for 9.5% of US vehicle sales in 2024, up from 3.2% in 2020. These trends signal that EVs are not a niche but the future of mobility.

US legacy automakers risk falling behind if they resist this transition. By lobbying to delay California’s 2035 EV plan, companies like GM and Ford threaten to cede ground to EV-only brands such as Tesla, Rivian, and Lucid. These newer players are fully committed to electrification, with Tesla alone commanding over 50% of the US EV market in 2024. Rivian and Lucid are gaining traction with premium electric trucks and luxury sedans. If legacy automakers slow their EV investments, they will struggle to compete with these agile, EV-focused brands that are capturing market share and consumer loyalty.

Meanwhile, Chinese automakers are accelerating their EV ambitions, posing a long-term threat. Companies like BYD and NIO are making significant inroads in Australia and Europe, with BYD’s affordable Atto 3 SUV becoming a top seller in Australia. China is the world’s largest EV market, with over 50% of global EV sales in 2024. Chinese firms are investing heavily in innovation. They are not lobbying to slow progress. They are producing cost-competitive models with advanced features. By 2035, Chinese brands are likely to enter the US market (even if that means buying out US brands to gain a foothold). If US automakers stay on the Luddite path, they will not be prepared to face the fierce competition from these global players.

Even if the current US administration supports delaying EV mandates, this will not ensure the competitiveness of legacy automakers. Short-term policy reversals cannot halt the global shift toward electrification. Delaying EV adoption risks leaving US companies unprepared for a future where EVs dominate. To remain competitive by 2035, US automakers must embrace the EV revolution right now and invest in innovation, rather than using political obstructionism to cling to outdated technologies.

The US has a storied history with automotive innovation, and companies like Tesla, Rivian, and Lucid are now leading the charge in the EV revolution, showcasing American ingenuity on a global stage. These homegrown brands have set benchmarks for performance and sustainability, with Tesla’s market dominance and Rivian’s rugged electric trucks capturing the nation’s imagination. Meanwhile, legacy automakers like GM and Ford are steadily adapting, contributing to the EV landscape with models like the Chevrolet Equinox EV and F-150 Lightning, even if they’ve been slower to pivot. The presence of Chinese EV brands like BYD and NIO in the US market underscores global competition, yet American innovation continues to shine.

This July 4th, as families gather for barbecues and fireworks, the most patriotic thing our politicians could do is to support American-made innovation, put the US on track to be globally competitive, and stop trying to drag our energy policy back to 1950.

Summer Solstice 2025

Image via Tesla

In the northern hemisphere, the summer solstice occurred on June 20th this year. It unleashed a sun-soaked bonanza of free energy for folks with solar panels glinting in the sunshine on their roofs. Those sleek photovoltaic babies soak up rays and churn out the kilowatt-hours right where you need them. This slashes those pesky transmission losses that nibble away 5-10% of grid power like a sneaky snack thief. With solar, your roof becomes a mini power plant, fueling your home with clean, sun-kissed juice.

Pair your solar with a home battery, like the Tesla Powerwall, and you’re the superhero of the cul-de-sac. You can laugh off blackouts while your neighbors fumble for flashlights. Summer’s here, and with it come those long sweltering days when air conditioners hum like a buzzing swarm of caffeinated bees, working overtime to keep your home cool, stressing the grid to the brink. Solar panels swoop in like a cool breeze, powering your AC and easing the grid’s sweaty burden, helping keep the lights on citywide.

Got an electric vehicle? Charge it with sunshine! Tesla’s Charge-on-Solar feature lets you juice up your EV straight from your rooftop rays, turning your Tesla into a sun-powered chariot. You can zip past gas stations, grinning as your car runs on free solar swagger. If your panels are pumping out more juice than your home and EV can gulp, the excess spills onto the grid, powering your neighbor’s Netflix binge. Net metering can score you credits, shrinking your electricity bill faster than a popsicle in July. And if your utility has VPP events, you can even get a fat check.

Solar has never been cheaper, with costs plummeting more than 50% over the last decade. A 6-kilowatt system runs $10,000-$15,000 before a juicy 30% federal tax credit (which may not be around for much longer). Financing means you can start saving with pocket change upfront, and your electric bill savings often outpaces the loan payments. Systems can pay for themselves in 5-10 years. Then, once they are paid off, it gets even better. Electricity rates might keep climbing, but you won't care.

Rooftop solar isn’t just smart; it’s your ticket to a cooler, greener, and brighter future.

One Sunny Day

Here's our solar data from a few days ago. You can see by the color where the solar energy was directed. The first thing to note is that production started at 6AM and finished at 8PM. That's 14 hours of production, peaking around noon at 8.3kW. 

You can see that the early morning energy went into the battery. Then at 7AM, when the higher Time-of-Day rates started, the solar was redirected to run our home (shown in blue). Any energy beyond the home's need was directed into our EV (red). By 10AM, the car was charged, then the Powerwall (green) soaked up the extra juice. Before noon, the Powerwall was full; then the surplus solar flowed into the grid (grey), running our meter backward and powering other homes on our block.

You can see the large spikes of blue in the afternoon; this was the AC cycling.

We have many more net-positive days like this one ahead of us.

PGE VPP :: Smart Battery

Smart battery image by ChatGPT

Portland General Electric (PGE) started their Virtual Power Plant (VPP) pilot (called SmartBattery) in the fall of 2020. We were among the first to sign up for the program. This 5-year pilot program is coming to an end soon, so what happens next?

The pilot (unsurprisingly) hit a few start-up snags in the beginning. However, that is the point of a pilot (find out what you don't know on a small scale, learn, adapt, then deploy on a larger scale). The good news is that PGE learned lessons and made changes. In one case, I know they made a change specifically based on my data, as evidenced by an email they sent specifically to me stating that they were improving support for "super users" based on my system specs and usage. 

They have also made changes to the method to determine participant payment amounts. Initially, PGE used a system similar to the Smart Thermostat program. You were paid $20 for each month that you were enrolled, regardless of participation. This has obvious issues: someone who participated in five events in a month would be paid the same amount as someone who participated in only one, and this does not account for the level of participation in each event (during an event, did you send 1 kWh or 50 kWh?). Obviously, the incentive needed to align with the value provided, and PGE changed the participation payments accordingly.

What's Next?

This was a 5-year pilot, and it is coming to an end in September. Approximately 450 households are participating, and we want to know what's going to happen when this pilot ends. The good news is that PGE wants to continue the program and move it from pilot phase to a full-fledged program. 

The proposal for the new SmartBattery program must be approved by state regulators and CUB. I don't expect anyone to oppose this program; it's a win-win for the utility and participants: it helps stabilize the grid, and reduces CO2 emissions, while paying participants.

Benefits of VPPs

VPPs integrate distributed energy resources like solar panels, batteries, and demand response systems into a cohesive network. They optimize energy distribution, enhancing grid reliability and efficiency. By aggregating small-scale energy sources, VPPs provide utilities with flexible, cost-effective alternatives to peaker plants, reducing reliance on fossil fuels. 

VPPs enable real-time energy management, balancing supply and demand to prevent outages during peak demand hours. VPPs also lower energy costs for consumers by prioritizing cheaper, renewable sources and reducing transmission losses, rather than firing up the most expensive and dirtiest sources available. 

VPPs also enhance energy resilience, allowing communities to maintain power during outages by leveraging localized resources. They are the first step to the internet of energy, supporting grid modernization, and integrating smart technologies for better forecasting and control. Additionally, VPPs create economic opportunities by enabling participants to earn incentives for sharing energy. As renewable energy adoption grows, VPPs will play a critical role in building sustainable, decentralized energy systems, ensuring affordability, reliability, and environmental benefits for all.

EVs Must Pay Their Fair Share

Proposed $250 Federal EV Registration Fee: Fair Share or Political Ploy?

Two guys stroll up to a bar. One’s clean-cut, suit pressed, looking like he just stepped out of a cologne ad, while the other guy’s a mess, wearing stained sweats, reeking of smoke and body odor, dirt smudged on his face, and a cigarette dangling from his face. The doorman eyes them both, smirks, and says to the clean guy, “That’ll be $25.” Then he turns to the mess and goes, “You’re good for $10.” The clean guy sputters, “What?! Why am I paying two and a half times more?” The doorman chuckles, “Buddy, you’re too clean, you’ll make everyone else in the bar look bad. We charge extra for that!”

Well, it looks like the federal government has hired this doorman. A new federal proposal imposes a $250 annual registration fee on electric vehicles (EVs), arguing they use roads and should contribute to maintenance like gas-powered cars. The logic seems clear: roads need funding, and EVs (like all vehicles) use the roads, highways, and byways. But is $250 fair, or is it a move to hinder EV adoption? Let’s dive in.

Gas-powered cars fund roads via the federal gas tax, set at 18.4¢ per gallon. The average US driver covers about 13,500 miles annually, and a typical gas car gets roughly 25 miles per gallon. After a little number crunching, this means the average driver pays $99.36 in federal gas tax per year. Compared to the proposed $250 EV fee, EV owners would pay over 2.5 times more than gas car owners for the same road use.

Vehicle Type	Annual Mileage	Fuel/Tax Type	Annual Cost
Gas Car	13,500 miles	Gas Tax (18.4 cents/gal, 25 mpg)	$99.36
Electric Vehicle	13,500 miles	Proposed EV Fee	$250.00

What’s a fair share? Since EVs use roads similarly to gas cars, their contribution should align. The $99.36 gas tax benchmark shows the $250 fee is excessive. A fair EV fee would match gas car contributions, around $100 annually, possibly adjusted for mileage. This ensures equity without penalizing EV drivers.

If either vehicle type should pay more, gas cars should be the ones to pay additional fees because of all the externalities they hoist onto society. EVs deliver community benefits that gas cars can’t match. EVs produce no tailpipe emissions, reducing air pollution and health costs tied to smog and respiratory issues. Studies estimate gas-vehicle-related pollution costs the US billions annually in healthcare and environmental damage. EVs help curb this. Additionally, funds spent on EV “fuel” (e.g., electricity) stays local, bolstering utility companies and renewable energy investments. In contrast, gas money often flows to oil companies and foreign markets, siphoning money from local economies. For all of these reasons and more, EVs deserve fair treatment, not a steep fee. EVs are the hometown heroes.

I didn't buy an EV as an elaborate (and expensive) scheme to avoid road maintenance taxes, but that doesn't mean i want to overpay either.

The $250 fee reeks of political maneuvering to slow EV adoption. It burdens clean, efficient vehicles while dismissing their societal benefits. It is not a fee because the roads need funding; it's a fee for making gas cars look bad. It's charging the clean guy at the bar extra just for looking good.

If this is the right way to raise funds, then let's apply it to every vehicle. Cancel the federal gas tax and make everyone pay the same amount to use the same roads.  

Policymakers should focus on building an infrastructure for the current century, rather than the 1900s. Impeding progress will only put us behind. Sure, EVs must pay their share, but charging them far more than gas cars is neither fair nor forward-looking. It’s a roadblock to a cleaner future. It’s like charging joggers more for park trails if they _don’t_ litter. It’s absurd! EVs need to chip in, but this fee is a pie-in-the-face of progress. Let’s not let gas-guzzling dinosaurs and their cronies drag us back to the Jurassic era.

Waymo is the Hydrogen Solution of Ride Hail

Image by OpenAI

Both hydrogen fuel cell vehicles and Waymo’s autonomous ride-hailing service are technical marvels, yet both stumble on the steep slope of scalability, especially when costs come into play.

Hydrogen fuel cell vehicles, such as Toyota’s Mirai and Hyundai’s Nexo, power electric motors through a clever process: hydrogen stored in high-pressure tanks reacts with oxygen in a fuel cell, generating electricity to power the motor and drive the vehicle, with water vapor as the only byproduct. A full H2 tank is about 5 kilograms, and this delivers a 300 to 400-mile range. Refueling takes just five minutes. Technically, it works beautifully. The Mirai cruises highways and city streets, matching gasoline cars for refueling convenience and outshining them for emissions.

So why aren't we all driving zero-emission H2 vehicles today? Price and scalability are the roadblocks. Building a hydrogen refueling station costs $1 to $2 million, and the US has only about 50, mostly clustered in California. Compare that to 120,000 gas stations or 50,000 EV chargers across the country. Then there’s the fuel. The cost to fill up a fuel cell car in California is around $16.50 per kilogram. A Toyota Mirai with a 5.6kg tank would cost around $92 to fill up. However, Toyota (and others) offer free fuel for the first three years to help bridge the price gap between hydrogen and gasoline. Assuming owners had to pay for the H2, let's compare the cost per mile. For a Toyota Mirai, it's around $0.31 per mile. Compare that to $0.12 per mile of a gas car and H2 as fuel is like paying $9 per gallon for gas. No one wants to do that. This explains why they have to give away years of free fuel just to sell (lease) the things.

Scaling FCVs to millions of users would require thousands of stations and cheaper hydrogen, demanding billions in investment. High costs keep FCVs a niche player, not a mass-market contender.

Now, let’s shift gears to Waymo, Google's Alphabet’s self-driving transportation service. Waymo’s fleet of modified Chrysler Pacificas and Jaguar I-Paces uses LiDAR, radar, and cameras to navigate without a driver. AI processes a 360-degree view, dodging pedestrians and traffic with precision. It works. Waymo’s vehicles log thousands of miles in cities like Phoenix and San Francisco, safely delivering passengers. But, like hydrogen FCVs, scalability is a struggle. A Waymo vehicle with its sensor suite and compute costs around $100,000, though bulk production might trim that. Operating costs pile up fast: maintenance, software updates, and remote human oversight push per-mile costs to $2 to $3, dwarfing the ~$1 of a human-driven Uber ride. Waymo has raised $5.6 billion, yet profitability lags. Each ride is subsidized, and scaling to millions of vehicles means building charging stations, service hubs, and data centers, costing billions more. The tech is solid, but the price tag for widespread adoption rivals the challenge of hydrogen’s infrastructure.

Both Waymo and hydrogen FCVs prove the possibility of the technology. FCVs glide along, emitting only water, while Waymo’s cars steer through chaos without a human hand. Yet both hit the same scalability wall: cost. Hydrogen’s refueling stations and fuel production demand massive upfront investment, just as Waymo’s sensors, operations, and infrastructure do. Neither technology is cheap enough to flood the market. FCVs need a vast network and affordable hydrogen; Waymo needs leaner tech and lower operating costs. At CarsWithCords.net, we admire the ingenuity, but the path to scalability looks daunting. For now, both remain bold experiments, waiting for a cost breakthrough to drive them mainstream.

Lidar or Camera, Which Sensor Will Win for Autonomous Vehicles?

 Autonomous Driving: A Revolution in Motion

Imagine a world where getting around is as easy as tapping an app, no matter who you are. When autonomous vehicles hit the mainstream, they’ll rewrite the rules of personal mobility. For the blind or elderly, who often face the isolation of being homebound, self-driving cars promise freedom. No longer will a lack of driving ability mean missing doctor’s appointments, social gatherings, or simple errands. These vehicles will be like loyal chauffeurs, ready to whisk anyone, anywhere, safely and reliably. This isn’t just convenience; it’s a lifeline to independence.

Tesla wants to be a primary transportation provider with their Robotaxi service, launching in June of this year. What's different about Tesla's implementation is that it is camera-based and could scale very quickly. Unlike competitors leaning on pricey, specialized sensors like LiDAR, Tesla bets on common cameras as its primary eyes. Vehicles with LiDAR and trunk-sized datacenters might work in select test zones, but they’re like gourmet dishes only available at a few elite restaurants. Tesla’s approach is the food truck of autonomy: affordable, adaptable, and ready to serve the masses. Scalability matters if we want self-driving cars everywhere, not just in elite regions.

I received some feedback on the last article saying that LiDAR was a must-have for safe autonomous driving, but let’s debunk that. LiDAR (LIght Detection And Ranging) uses laser pulses to map surroundings. It is very useful in many applications, but it also has serious blind spots. LiDAR cannot see the color of traffic lights or detect when another car’s brake lights are on, both of which are critical for safe driving. LiDAR struggles in bad weather, as rain, snow, or fog scatter the laser pulses, clouding its view. Plus, LiDAR is expensive, driving up costs for vehicles; affordability is required for a mass-scale solution.

LiDAR-based systems use cameras to catch what the lasers miss, like traffic light colors. That's right, all autonomous vehicles (LiDAR or not) use cameras. However, having both LiDAR and camera input leads to the sensor fusion problem. Sensor fusion is the artful science of blending data from multiple sensors. Combining these different sensor streams creates a problem: What happens when sensors disagree? If one sensor claims it’s raining while another warns that you're heading towards a brick wall at 70 MPH, which do you trust? This clash can confuse the driving AI, causing the AI to make poor or dangerous decisions. Tesla’s camera-only approach sidesteps this by providing one consistent data stream to the AI’s path planning and decision-making processes.

Autonomous vehicle (AV) cameras often sense beyond the human-visible light spectrum, which spans ~400 to 700 nanometers. Many AV cameras also detect shortwave length infrared light, from 700 up to 1100 nanometers, allowing them to see in the dark for improved night vision. This gives AV cameras an edge over human eyes. At night, these cameras excel, capturing clear images in near darkness.

Because AV cameras cover a spectrum of light frequencies, including visible and shortwave infrared, they have an advantage over LiDAR's single laser frequency. The broader spectrum of the cameras allows them to capture diverse visual data. In a way, cameras are already receiving multispectrum data that's "pre-fused" to a single video stream. LiDAR, on the other hand, operates at a fixed frequency (typically 905 nm or 1550 nm). LiDAR excels at depth mapping but misses color and texture details.

The question is, will Tesla's camera-based FSD be safe enough? Crashes will happen at some point. Every AV program of note has had incidents. A fatal crash ended Uber's self-driving program. We'll see if Tesla can navigate this rubric.

Autonomous driving is poised to transform lives, especially for those sidelined by mobility challenges. Tesla’s scalable, camera-driven solution is like that trusty food truck, bringing freedom to every corner, not just the fancy neighborhoods. By avoiding LiDAR’s limitations and the ambiguity of sensor fusion, Tesla is cooking up a future where self-driving cars will be as common as smartphones. This isn’t just about getting from A to B; it’s about giving everyone a ticket to ride, no matter their circumstances.

Tesla’s Robotaxi Launch: A Game-Changer for Mobility and Safety

Image by OpenAI

Tesla’s robotaxi service is gearing up for its June 2025 launch in Austin, Texas, setting the stage for a new era in transportation. This isn’t a full-throttle rollout but a deliberate “crawl, walk, run” approach, ensuring safety and reliability. The initial launch will be for invitation-only riders, starting with a small fleet of 10 to 20 Model Y vehicles in a geo-fenced area of Austin, Texas. How fast things will move to walk and run depends on how this service goes over the initial weeks and months. Tesla plans to expand to a second city (likely in California or Texas) by late 2025. In 2026, customer-owned cars and Cybercabs will be added to the network. This phased strategy allows for continuous iteration, a hallmark of Tesla’s innovation flywheel that drives rapid improvement in its products and services.

Tesla’s history of fast iteration is evident in its product evolution. Take the Model S: the 2025 version boasts superior performance with quicker acceleration, a range exceeding 400 miles, and a price point far more affordable than the 2012 original, which started at over $100,000 with a range of 265 miles. Similarly, the Powerwall has seen dramatic advancements. Powerwall 3, released in 2024, offers higher energy capacity and better grid integration compared to the first version from 2015, making Powerwall 3 a cornerstone of home energy solutions. This innovation flywheel will propel the robotaxi service, with each software update refining the ride-hailing features in the app and the Full Self-Driving (FSD) technology that drives the cars.

           

The robotaxi launch could redefine urban mobility by leveraging the innovation flywheel to deliver transportation that's electrified, safer, and more accessible for all.

For individuals with limited mobility, such as the elderly or those with disabilities, this service will be a game-changer. Over 50 million Americans face mobility challenges and cannot drive, often relying on expensive or inconsistent alternatives. Tesla’s robotaxis will provide on-demand transportation, empowering people with newfound independence. Whether getting to medical appointments, the grocery store, or visiting loved ones, the service promises to bridge a critical gap, aligning with Tesla’s mission to make sustainable transport accessible to all.

The backbone of this initiative is Tesla’s FSD technology, which is pivotal for convenience and safety. Human error accounts for 94% of U.S. traffic incidents, leading to over 40,000 deaths annually. FSD aims to drastically reduce this number. While the current supervised FSD achieves about 500 miles between critical disengagements, Tesla’s data-driven approach is rapidly improving its neural networks. With its unblinking multi-directional eyes, FSD will be an order of magnitude safer than human drivers, potentially saving countless lives by minimizing crashes. The robotaxi fleet will also help reduce emissions, which again saves lives and improves quality of life.

Tesla’s journey with robotaxis won’t be without challenges. Regulatory hurdles and public skepticism loom large, especially given past delays in FSD deployment.

The National Highway Traffic Safety Administration (NHTSA) requires an exemption for driverless vehicles such as the Cybercab. The permit process can take over a year, as seen with Nuro’s efforts. While Tesla has received a preliminary transportation charter-party carrier permit in California as of March 2025, further approvals from the California Department of Motor Vehicles and Public Utilities Commission are still needed. Given these factors and Tesla’s track record of delays (every initial vehicle release other than Model Y has been late, such as the Cybertruck’s late 2023 delivery after its 2019 unveiling), the Cybercab’s release could realistically slip into 2027 or later.

However, the company’s track record of iterative improvement through its innovation flywheel offers hope for this service. As Tesla collects real-world data from its initial Austin rides, each iteration will make the service safer and more reliable. For those who can’t drive and for a future with fewer auto-related deaths, Tesla’s robotaxi launch is a monumental step toward a safer, cleaner, more inclusive world of transportation.

To the Moon and Back Again 138,562kWh

image by OpenAI

On November 8th, 2024, our home solar system crossed a milestone. On that day, the solar panels on our roof produced their 138,562nd kilowatt-hour of energy.

What's so special about 138,562 kWh?

A 2018 Tesla Model 3 uses 29 kWh to drive 100 miles (newer ones are likely better). The Moon is about 238900 miles from Earth. Given this efficiency and distance, it would take 69,281 kWh to drive to Luna. Double this amount, and you could make the return trip. 

Obviously, you cannot drive to the Moon, but at least one car is in space.

For one more fun data point, this is enough energy to drive around the equator more than 19 times.

Tesla Model Y Winter Range

Image by OpenAI

How far can a Tesla drive in the winter? 

We've had our Model Y for two winters, and I've been tracking its driving efficiency year-round since we got it. I've heard it said that EVs have less range in the winter, and I wanted to see what our real-world data shows. 

Winter driving is generally less efficient. The cold air is thicker, energy is used to warm the cabin, and the extra traction of winter tires comes with a higher rolling resistance.

We get some snow here each winter, and we like to go to the mountain occasionally, so we have a set of winter tires. Tires can have a big impact on range, so here's the tire data and other relevant specs: 

Vehicle: 2023 Tesla Model Y Long Range All-Wheel Drive (AWD), an all-electric, mid-size crossover SUV.

All-season Tires: Continental ProContact RX 255/45 R19 104W XL. These tires came on our Y when we picked it up, and we drive on them from mid-March through October.

All-season Wheels: 19" Gemini Wheels, standard on the 2023 Tesla Model Y Long Range AWD, dark grey with plastic covers for improved efficiency. 

Winter Tires: Michelin X-Ice Snow 255 /45 R19 104H XL BSW. These are premium winter tires designed for EVs, crossovers, and SUVs. They're studless and rely on tread and compound for grip, rather than metal studs. They're built to handle severe winter conditions like heavy snow, icy roads, and sub-zero temperatures, while still providing decent dry-road performance. This model is a step up from its predecessor, the X-Ice Xi3, with better hydroplaning resistance and snow traction. We use these tires from November through mid-March.

Winter Wheels: Vision Cross II 19" X8 5-114.30 38 BKMTXX
These are cast aluminum wheels. They are slightly heavier than the OEM Gemini wheels and don't have aero covers. However, the matte black goes well with the modern chrome delete look of Tesla vehicles.

2023 Model Y LR	All-Season	Winter
Wheels	Gemini	Vision Cross II
Tires	Continental ProContact RX	Michelin X-Ice Snow
Miles Driven	7,457	6,182
Ave Temp	71F	50F
Wh/mile	254	278
Rated Range	330 miles	301 miles
Measured Real Range	302 miles	276 miles
Winter Penality		8.6%

The winter range loss is lower than I expected. The tires are not as efficient, the wheels are not as light, there are no aero covers, the heater has to run... and yet, there's only a ~9% range penalty. I was expecting it to be about 30%. 

One of the reasons this winter penalty is low is that Tesla vehicles have a very efficient heat pump. The heat pump includes a liquid-cooled condenser loop and an 8-way octovalve. This enables 3 cooling modes and 12 heating modes, including special modes for temperatures below -10°C. The heat pump uses a compressor that operates on 400 volts and draws power directly from the traction pack.

It's important to note that this data is for my NW Oregon driving. If the seasonal temps are different in your region, the results could be dramatically different.

Musk & His Haters Be Damned, I'm Not Selling My Tesla

In Defense of Tesla Owners 

Look, I get it 

Every time Elon Musk tweets something wild (like comparing hard-working civil servants to genocidal gas chamber workers, taking a chainsaw to social security benefits, suggesting we colonize Mars with only crypto-paying technocrat libertarians, or whatever his latest unhinged rant is), my inbox lights up. “You still driving that Tesla? You cool with that guy?” 

Let’s pump the brakes on this. We've asked the question, "Can you Love Tesla and Hate Musk?" The answer is, was, and will continue to be "Yes." Owning a Tesla doesn’t mean I support Musk or his politics. I didn’t sign up for a cult when I bought this car. I signed up for a sweet ride that doesn’t guzzle gas. That’s it. Full stop.

Mission  

Tesla’s whole deal is ditching fossil fuels for cleaner transportation and renewable energy. This didn’t suddenly become irrelevant because Musk decided to play DOGE lord. The planet’s still cooking, oil still has its greasy fingers in our energy policies, and I’d rather not choke on smog, thanks. Musk’s politics might’ve taken a hard right into Crazytown, but the physics of climate change didn’t RSVP to that party. Tesla’s mission matters, and it’s bigger than one guy’s midlife crisis meltdown. 

           

My hatred of Musk's antics is not greater than my desire to mitigate climate change.

Musk is not Tesla 

Newsflash: Elon isn’t even the whole Tesla enchilada. He’s just one of 125,000 people who have an active Tesla work badge. Sure, he’s the loudmouth at the top, but he only owns about 13% of the company. That means if enough shareholders vote to remove him, he's gone. So when you’re side-eyeing me for rolling up in my Model Y, just know I’m not exactly bankrolling his next X tirade about the woke mind virus, free speech, or whatever.  

           

I’m supporting a massive team of Tesla engineers, designers, and workers, many of whom roll their eyes at Musk as much as you do.

Vandalism Isn't The Answer

Apparently, some righteous warriors think keying a Tesla or smashing a window is a noble protest against Musk. Real genius move, punish the car owner who’s just trying to get to work without burning dinosaur juice. And, where do you think that damaged Tesla is likely to go for service? To a Tesla service center, obviously. And that means that Tesla will receive revenue for that transaction (even if it's from the owner's insurance company). So, your vandalism is actually a move of financial support for Tesla. I know that's not what you wanted. So chill and try not to force your ideals onto other people through terrorism. That's the sort of fascist action that might cause people of your ilk to get upset. If you want to peacefully protest at a Tesla store, go for it, but the line clearly stops at destruction of property.

Here's another idea: if you're thinking about vandalizing a Tesla, maybe you should talk to some owners about why they drive it, their goals, and maybe you'd see that you have many things in common with them. And guess what, even if you don't, it doesn't mean that you get to damage their property.

Personal Finances are Personal

You don't get to tell me I "have to" get a new car. Cars aren’t cheap. I didn’t drop a small fortune on this thing just to trade it in because the CEO said something spicy or some punk with a grudge and a spray can thinks "swasticar" is a super clever insult. Whether you’re cruising in a Cybertruck that looks like a Halo prop, a sensible Model 3, or even a Prius with a “Coexist” bumper sticker, most of us can’t afford to swap vehicles every time the political winds shift. And even if you’re some trust-fund baller who buys cars like I buy socks, that’s a dumb way to virtue signal.

The Alternatives?

Here’s another fun fact: if you dug into the personal lives and politics of most Fortune 500 CEOs, you’d probably need a shower and a stiff drink afterward. These greedy, out-of-touch, maybe even low-key psychopathic people aren’t exactly BFF material. Musk isn’t special in that regard; he’s just the one with a megaphone and zero filter. The rest of them are quietly yachting with shady billionaires while we’re none the wiser.

Nothing Compares To Tesla

But here’s the clincher, the real reason I’m not selling my Tesla: I freaking love this thing. The tech is bananas. Full Self-Driving is (finally) getting really good. The charging network is unmatched. Try finding another EV with Tesla's range, performance, cost, and a network with even half as many locations—it doesn't exist (at least not in the US). I’m not ditching an EV that I love for some clunky alternative just because Elon’s out there cosplaying Tony Stark with a dose of conspiracy theorist or because some edgelord thinks I’m the enemy because of my ride. I don't have to defend my purchase with an "I bought this before Elon went crazy" bumper sticker (but I understand if you want to). My reasons are my own and I would still buy the same Tesla vehicle today. Sorry, not sorry haters; this Tesla’s staying in my garage. In a few years, perhaps there'll be a worthy competitor to consider.
