They partially solve the fuel and the bad air problems. In exchange they damage roads way more (I recall reading that the damage is proportional to the vehicle weight to the fourth power, probably with some more nuance) and that also creates substantially more rubber micro particle pollution. They also happen to be more dangerous in the event of a crash. Plus the additional challenges with grid load, which some people dismiss with silly ideas like having said cars act like load balancers (that would be a mess to scale).

In most cases, EVs are not a solution to mobility, they are a solution to save the car industry from real solutions to climate change, namely spamming trams, trains and buses (in sparse locations) all over the place.

Yes. Road damage is based on vehicle weight. To the 4th power, yes. Heavier vehicles do exponentially more damage than lighter ones. https://www.hagerty.co.uk/articles/opinion/opinion-cars-have-a-weight-problem-and-its-damaging-more-than-the-environment/

But actually it's based on axle weight. This is why Semis have many axles, to spread the weight out.

But actually it's based on tire weight. This is why Semis have doubled wheels on their axles.

But actually it's based on contact pressure. This is why Semis have wider tires than your standard car.
