Sure, easy enough to legislate all new vehicle sales be EV by 2035. Similar laws have been written in the past to tighten emissions requirements, and car makers have had to comply. No real issue with that.

My question is by mandating EV, you are now tinkering with the transportation support infrastructure. We could have had EV's that run on hydrogen fuel cells twenty years ago. The problem wasn't designing and building the cars. The problem was refining and distributing the hydrogen. There just simply isn't the infrastructure to pull that off on a massive scale. Putting it in place would cost billions, and every party involved is going to think it isn't their problem.

We're kinda in the same boat with pure EV. Where is the infrastructure to charge vehicles going to come from? Can the grid handle the extra load? A homeowner with a garage can install a car charging station and charge their car at night, but what do people in townhomes or apartments do? I could see this being a major problem for dense urban areas.

Wonder what happens when the electric utility submits their proposal to triple the rates they charge to handle the infrastructure upgrades required. Probably more than that if states insist that cars be charged using fully renewable energy too.
