Charge times will continue to be an issue, less so for cars and increasingly more for all of these vehicles that this law wants to replace, A 70-100kwh batteries are one thing but when you need the energy density of 300kwh+ you're running into Tesla Semi requirements on a pickup. Sure it will eventually get there but how does legislation guarantee it will be 2040 or sooner like you think, and why is legislation needed if the tech already is or will be so great? Why spend funds sorting registrations and denying them or whatever? if the tech is there, people will use it. And this proposed law does nothing to stop someone from bringing in a car from out of state.
