It is the law in 13 states. The implementation of the mandate is set for 2035. That doesn't change that those states are mandating it.
Doesn't change that it's a government mandate. If you want to buy a car, you are going to be limited to choices the government gives you with no alternatives.
Sure, but then you can't register it in the state you live in because of the mandate. It says all cars of a certain year model on must be EV. So, you buy an 2036 ICE vehicle, and your state says EV's only, you can't register it in the state in which you live. It is also already illegal to live in a state and have your car registered out-of-state unless you just moved there, and then you only have a short window to re-register the vehicle.
