Infrastructure is a big consideration that is sort of glossed over by governments enacting legislation to force the adoption of electric cars. When gas powered cars initially came about, law makers and manufactures had to go to some lengths to set up an infrastructure for fuel delivery and accessibility. It wasn't just about making the cars, a whole system had to be deployed.

Not much thought about infrastructure has gone into the adoption of electric cars. It could easily end up being a situation where there's too many cars and not enough support. The EU is already thinking ahead, but I think its likely the USA will get caught with their pants down.

For example California has already enacted legislation forcing all new cars to electric after 2035, but has not passed any legislation about infrastructure for them. There are over thirty million privately registered cars in California. You need places to charge all of them and support the power demand for it. The power grid in its current state would not be able to do it. They already have problems when existing demand gets too high. So it's not going to be a small issue by any means.
