I am talking about taxation and being able to provide essential services. Not everything need to turn a 'profit' but government budgets are not unlimited.

Would you entertain the idea of people generally living in the city, but needing to commute to at least the factories and logistics centres?

Commuting doesn't have to be by cars, nor should factories and warehouse should be prohibited out of hand from being located inside cities. It really depends.

Even then, it still makes sense to aggregate industrial concerns within a given area to benefit from colocation of related industrial facilities and make it easier to commute via public transit.

Farms on the other hand should be subsidized. This is also where cars usually makes the most sense.

Granted, I would still rather them designed for lighter weight. But that’s a separate issue w suv culture which is bad for society and environment in general. Totally would buy a 3000 pound EV around the size of a euro hatch.

I believe that cars of this size should be the most common vehicles on the road. They efficiently meet the transportation needs of most people while consuming significantly fewer resources than larger cars. However, for decades, American consumers have been influenced by marketing campaigns promoting larger vehicles. This trend began when Ford and GM sought to protect their market share from smaller, more fuel-effici…

Not just marketing campaigns: also federal CAFE fuel efficiency standards that have a lower efficiency requirement for light trucks (including SUVs) than for passenger vehicles. https://www.vox.com/future-perfect/24139147/suvs-trucks-popu...

They do. But if you brake too agressively, they switch to friction brakes. It pays off to avoid this: more mileage, marginally lower charging expense, lower cost on brake maintenance and fewer complaints from passengers.

Apparently you need to use the friction brakes now and then so they don’t degrade early, which could be a safety issue. I think as long as you’re using the car frequently it’s incredibly unlikely to be a problem though.

Yup. I only use my car infrequently and it sits there with the handbrake on, when I do take it out often the rotors have rusted just slightly, meaning I get a "thunk thunk thunk" until I brake hard a couple times.

I think it's fine, in an EV just give your physical brakes a good test/try out when starting a journey in the car, especially if it has been sat for a while.

The Yale article and the paper both highlight the fact that EVs use regenerative braking and produce less dust. I was worried that this was a rehash of the astroturf campaign from a few years ago focusing on EV weight and how that was so bad for the environment because of tire and road wear. Unfortunately you need to read through the whole thing (instead of the headline and a few paragraphs) to see that information.

People also nearly always forget to account for the traction control of EVs vs. ICEs.

EVs have a faster electronic traction control system that results in less tyre spin, which results in less wear on both the tyre and, in the case of winter, the road itself, as studded tyres eat away at the asphalt.

EVs can be pretty bad for tire wear, not just due to vehicle weight, but the amount of torque available (and consistently available) that leaves most ICE vehicles in the dust. Depends on driving style of course

Sounds like emission standards need to be updated to include everything coming off a vehicle, not just out of the tail pipe. It would incentivise clean disk materials and regenerative braking.

EURO 7 does include limits on breaks and tyre pollution.
