If you can charge at home, they’re an amazing deal. I think the vast majority of households with n >= 2 cars would be best served by [1..n-1] of them being an EV.

Even a ten year old Leaf for $4k is still useful to soak up the around-town driving that an average family does most of their miles in.

486sx33•4mo ago
Charging at home is part of the problem. They need to separately meter power for cars and increase the rate and add a road maintenance tax based on vehicle weight.
tzs•4mo ago
There's a dead comment by 486sx33 that says:

> Charging at home is part of the problem. They need to separately meter power for cars and increase the rate and add a road maintenance tax based on vehicle weight

I'm not sure why it was killed because that actually is an issue that has not yet been satisfactorily solved.

Many states pay for road construction and maintenance via a per gallon gasoline tax. Since EVs do not use gasoline they have turned to other ways to get EVs to help pay for the roads, usually by adding a flat annual registration fee.

In my state that flat fee is $150. That is equal to the component of state taxes on gas that go to roads on 270 gallons of gas.

If I had bought an ICE (non-hybrid) earlier this year instead of an EV I would have bought either a Honda CR-V or a Honda Civic.

I mostly do city driving. With the CR-V I'd have to drive 7300 miles to pay $150 toward roads. It would be 8600 miles if I mostly drove highway. With the Civic it would be 8600 city or 11000 highway.

I actually drive under 2000 a year, so if my EV driving patterns end up being the same as my ICE patterns I'm going to be paying a lot more toward roads than I would have had I gone with an ICE car.

It does look like my mileage will go up with the EV, possibly up to 5000 miles a year, but even then I'll be paying more toward roads than if I had bought an ICE.

I'd much prefer to have a mileage based road tax.

I'd be fine if they just looked at my odometer whenever I renew my registration and charge me then, but for a lot of people having to pay their entire share of road fees for their last year of driving at once would be difficult.

Separately metering my home charging and taking care of the road fee there would be great.

edgineer•4mo ago
I'm satisfied with the flat fee system. The cost difference is at most $150 per car per year, which is not much to argue over. It is more like eating into the savings from switching from gas to electricity, rather than an additional burden.

The premise of being taxed by mile driven is arguable. People benefit from roads even when they do not drive. AFAIU light passenger traffic has little bearing on the resultant maintenance costs, that most wear comes from heavy trucks.

I do not want separate meters complicating EV charging and accounting.

bombcar•4mo ago
They could tax the tires; if multiple states agreed to do it at the same time it'd work decently well.

Gas was a useful proxy (and let them tune cars vs semi trucks) but tires would work about as well.

tempaccount421•4mo ago
Tax by vehicle weight and miles driven per year is theoretically the most fair. Allowing the spreading of payments over the year would soften the blow.
rogerrogerr•4mo ago
I used to advocate for this, but it’s a regressive tax. Semi trucks do by far the most road wear, so would bear the most taxes in any fairly distributed system. Those trucks are how groceries get to stores, and groceries comprise a far higher proportion of a poor person’s spend than a rich person. Maybe you get some second order effects, but the first order effect is “grocery tax”.
maxerickson•4mo ago
For a portion of $150, do you really care all that much?
rogerrogerr•4mo ago
I’m much happier to pay the flat rate (we might be in the same state) on registration; the mechanism for enforcement already exists. I don’t want the state to grow a new facility to regulate how I use electricity - sounds like a permitting, inspection, and surveillance nightmare.

I bet the cost to permit and install a whole different metering system would be several multiples of $150.

bryanlarsen•4mo ago
AFAICT electricity companies like Octopus already have separate EV rates. They give you a lower rate for EV charging in return for flexibility on when your EV is charged.
bryanlarsen•4mo ago
There are much better articles addressing this topic. The good ones generally reference this study: https://www.geotab.com/blog/ev-battery-health/

Given that you can expect to get well over 200,000 miles and/or 20 years out of a large liquid cooled EV battery, there are some screaming good deals out there.

johnea•4mo ago
tl;dr Yes! They're a good deal!

I know some people who bought one of those little electric "golf cart" like vehicles to drive around the neighborhood.

It seems these cost between $15K and $30K!

I paid $15K for a used Nissan Leaf, with 150 miles of range, and a bit of the factory warranty still in effect.

Personally, I don't see why the Leaf gets such a bad rap. I would like more range than 150 miles, but this much serves all of my typical driving (including freeway, which the golf carts can't do at all).

The EV acceleration (and one-pedal driving) are awesome. No internal combustion vehicle can ever match the performance of an EV.

My expectation is that the overwhelming majority of people drive less than 150 miles the overwhelming majority of the times they leave the house, i.e. they almost never need the gas provided range.

I do still have a gasoline van that I use during long distance travel, but this is once or twice a year.

I think the overwhelming majority of objections only exist between the objector's ears.

I always charge in the driveway, and haven't bought gas in over 6 months.

Try it, you'll like it...

dyauspitr•4mo ago
They are. I’ve had my F150 lightning for about two years. On my old gas F-150 I used to pay about $150 a month in gas. On this one I pay about $18 on my monthly electric bill. I do live in a place with off peak electric prices of $0.07/KWh.

That’s not even talking about how silent they are, the amazing acceleration that makes driving a joy, you can leave them idling when you’re waiting with no toxic emissions/guilt, no oil changes and because of the regen braking the brake pads have to be changed very infrequently.

atombender•4mo ago
Did you buy it used? The F150 only came out in 2021. The article is about used EVs are a much better deal the gas cars, not whether EVs in general are better.
rogerrogerr•4mo ago
2021 was four years ago, which is more than two.
dyauspitr•4mo ago
I did not, it’s my general impression on EVs that should hold regardless.
afavour•4mo ago
> With a gas car, between age and mileage you know a lot about that car. In the EV, people have no clue,” said Helveston. Battery health, he explained, is more linked to how the car was used than its age or mileage

Does the same not apply to gas cars? In a different way obviously but the way any car has been driven in its lifetime affects its long term viability and you don’t have a great insight into it at purchase time.

nickm12•4mo ago
Agreed. Any complex mechanical device like a car can be "ridden rough", regardless of whether it is gas or electric. I feel like with gas cars there are a lot more moving parts to get stessed, while electric it's mostly about how the battery was treated. Having bought multiple used cars, including a used EV, it seems like a wash to me.
edgineer•4mo ago
Maybe it's worse with ICE cars--more parts, many considered wear items, that are difficult to get to to inspect. It could be hard to tell if the seller recently changed the oil and filters after never changing them. Transmission, alternator, etc. could have issues only intermittently.

Should be easy to see HV battery health, charge to 100% and check remaining range reported. Drive unit/other battery issues seem pretty rare and I'm not sure they're correlated with driving behavior, though I could be wrong.

jerlam•4mo ago
I'm not really worried about the traction battery. I'm worried about all the other components unnecessarily packed into the modern car (not exclusive to EVs) that may get damaged or fail and incur significant repair costs. Unfortunately I live in California where the gas savings from an EV aren't that significant.
potato3732842•4mo ago
> I live in California where the gas savings from an EV aren't that significant.

Which is a statement about electricity prices more than gas prices.

parineum•4mo ago
Given the price of gas in CA, it's a huge statement about electricity prices.
AtlasBarfed•4mo ago
So is there anything that keeps people from getting home solar in a state with high utility prices and high gas prices?
klooney•4mo ago
Cost and regulatory instability
willis936•4mo ago
Inflated costs due to over-regulation, high interest rates. People don't have $100k sitting around, especially people looking to cost optimize their commute.
AtlasBarfed•4mo ago
A hundred thousand? For home solar? In the state with a direct line to Chinese panels? In a liberal state that is desperate to get carbon neutral? Where you have fantastic year round sunlight?
willis936•4mo ago
Yep. BOM is about $40k, but the barriers to DIY are artificially raised. There is nothing complicated about these systems. It's a buck, BMS, inverter, and load switch.
dzhiurgis•4mo ago
Gear oil changes get forgotten, esp on high end Tesla’s. Not so important on lower end ones hut still needed.

Gas savings is oxymoron. You are getting a vehicle that drives at least 10x better. Can’t price that.

mlsu•4mo ago
I have a used (& paid off) Hyundai EV. It’s essentially the same form factor as a Prius. I cannot bring myself to part with it because it is such a smoking good deal. It’s low maintenance, it’s cheap to charge (on off peak), it’s efficient to drive, it can carry anything (9’6 surfboards? kayaks? A Bookcase? No problem).

I calculated it out and if I got a reasonable gas car it would be roughly 3 times more expensive per month to drive. It’s cheaper even than biking and taking the train to work (to be fair the train is expensive where I live).

I think this car will easily last another 150k miles with nothing more than tires and basic maintenance.

That said, I do miss an old stick shift gas car. EVs don’t give a feeling of life.

justinrubek•4mo ago
I think it may just be a personal thing about the feeling of a vehicle. All of my cars felt dead until I got into an EV. Now, I actually get giddy about using it and accelerating. Before it was just emptiness.
yurishimo•4mo ago
I think it definitely depends on your vehicle history. Going from an automatic 2004 Camry to a 2022 Model 3 will feel like a massive jump. But from a stick shift tuned golf? Less so…
nickm12•4mo ago
Yes! I just bought a dealer-certified three year old Kia Niro with 24k miles for $22k. The current new version of this car has an MSRP more than double that price. There is no world where the difference between these cars is worth $25k. In my head it's more like $10k-$15k max.
bdcravens•4mo ago
I bought my Kia EV6 at probably the worst time (fall 2022). EVs were in high demand, dealers were adding markups, and my credit was still reeling from just buying a house. As a result, I owe way more than I could buy it used lol. Not that I would (and ignoring the ramifications), but it would cost me less money to just let it get repossessed and go hunt it down and buy it from the used dealer that buys it at auction.
dzhiurgis•4mo ago
Lots of stories like this. I bought mine 2023 while subsidy was still there and Tesla just dropped prices. Yes it depreciated solid 25% but that equates to gas savings. Buying new would cost more now.
dzhiurgis•4mo ago
Change your gear oil asap. https://m.youtube.com/watch?v=dyAGPAM1rQM
bdcravens•4mo ago
My EV6 is right at 60k miles, and I don't see any issues with it that would keep it from going another 60000+. Used, it's probably $22k-25k, which to me would be an amazing deal.
dzhiurgis•4mo ago
Hyundai/KIA has been plagued with ICCU failures and reduction gear issues. Hard pass.
supermatt•4mo ago
I just had solar installed at my property and am producing more than I can store in the grid (rural lines restricting how many kW).

I was considering picking up an old leaf (or 2) as some buffer storage, so I can continue to feed excess energy into the grid during low solar periods.

Does anyone have experience of using a leaf in this way? Anything I should look out for when sourcing one?

beAbU•4mo ago
Not sure if the leaf is what you are looking for. Look for ev's with vehicle-to-home or vehicle-to-grid as a feature.

V2H coupled with the right "onshore" hardware is exactly what you want: the car battery is connected to your home grid, and the ev battery works in tandem with your home ESS batteries.

supermatt•4mo ago
I was surprised to find the leaf has actually supported bidirectional charging since its initial release, hence the choice as they are crazy inexpensive.

I’m assuming would need a bit more hardware to coordinate when and how fast it should charge and the feed into the grid, so it wouldn’t try and charge from the grid (only the solar) and it wouldn’t feed more than is permitted into the grid.

RickJWagner•4mo ago
I just made the decision to buy a car, my 2005 CRV was starting to require a lot of upkeep.

I strongly considered used EVs, but reliability concerns scared me. I like to keep cars a long time, and the idea of a battery or motor going out in a 9 year old car was a consideration.

I ended up going with a Corolla hybrid, getting 50+ mpg with every tank. Maybe next time I’ll buy electric.
