Just normal driving, it wasn’t quite so bad on our previous car which was a Nissan Leaf (with 30kWh battery) but our current Kia Niro just has a lot bigger batter (64kWh) and it is a lot heavier I suppose, the tyres just don’t seem to last as long. I’m pretty sure I’m using summer tyres all year round (I live in the UK) this was recommended by the dealer

remember, your regenerative braking comes at cost of tire life. If driving Tesla, you can reduce the regenerative breaking from Maximum setting to Medium. this will reduce regeneration and will increase the "breaking distance" when you just let go of accelerator pedal. but it will increase your tire life significantly. also make sure to buy the "commuter tire" models - tires with high mileage warranty (50k miles+) an…

Huh? What do you imagine is the tradeoff between regenerative braking and tire life? Are you suggesting that stopping the car with conventional iron brakes is somehow easier on the tires?

To some extent, but not really. Effectiveness of regenerative braking depends on having an extremely large battery that can sink enough current to stop the car. An EV can do that, hybrids at best help the brakes out some. You just can't charge the battery fast enough doing anything but a very slow rolling stop. My model Y can effect a very reasonable stop in traffic without touching the brake pedal except to hold the…

I test drove an EV and the regenerative braking was difficult to get used to. You have to constantly ride the gas pedal. I would buy an EV if it weren't for this feature.

> was difficult to get used to

To ask the obvious, how used to something are you going to get on a test drive? It takes time.

If all of us renters were forced to convert to electric there’d never be an open charger in any city again for the next five years, because no landlord will voluntarily afford that cost, and no municipal region can pass a ballot measure to afford that cost. California’s impending ban of combustion car sales hinges wholly on a magical DC-charging network that doesn’t exist in U.S. cities yet (i.e. at parking meters),…

Level 1 charging overnight on a standard 120V outlet, while not ideal, is surprisingly adequate. Granted, many people rely on street parking or otherwise don't have a parking spot that is right beside their dwelling, but for rented houses or complexes with private garages/parking areas the size of the lift isn't necessarily "get upgraded service and a bunch of 240V EVSE put in".

Yeah I’m charging an EV (with a huge battery) at home on 120v and it’s fine 9 out of 10 days.

I suppose the same should apply to hybrid cars, which outnumber pure EVs significantly [1]. The effect comes from converting the kinetic energy back to the battery charge via generation instead of wasting it via friction, which is the whole point of hybrids.

And manual transmission cars kinda, though the energy is still wasted of course

Depends on how you drive. I never engine braked on my manual. Brakes are easy to replace. Clutches are not.

This seems a bit exaggerated. Staying regenerative-only does require sticking to about half or so of how fast I could stop, but so far that seems to work fine unless a light turns right in front of me or traffic acts up. Usually it says it gets high 90's or 100%, and it didn't go below 50% even when a stoplight did turn at exactly the wrong time. (2022 Ford Escape non-plug-in hybrid, recently bought used.)

I’m against a ban. That sort of pollution is an externality and we could price it in.

Yeah, because that's worked so well in other sectors. You know how Tesla makes a fuckton of money? Selling their carbon credits to industry so they can pollute. So all the pollution reduction caused by people driving Teslas enables industry to pollute instead of controlling their emissions, reducing energy waste, decarbonizing, etc.

Isn't that exactly how carbon credits are supposed to work?

It's a combination of the weight of the vehicle and the torque that the electric motors produce.

That makes more sense, but if that's true, you can avoid the extra tire wear by driving like a granny (which reportedly works, according to one of the other comments here).

Well, if you can convince my wife of that, you're more than welcome to try. I just crossed 100k miles on my Model 3 and I think I'm on my 5th set of tires.

We should obviously ban combustion engine cars, at least starting with cities. I can’t think of a single clearer win for air quality.

Based on the long history of trying to price in externalities, bans are probably more effective. Just look at how many games are played with carbon "credits", and how little real impact they've had.
