I too think it will be quite a while before it is even possible to actually eliminate IC vehicles.
But there are cities in Europe that have laws in place banning IC vehicles in the future. Amsterdam in 2030 for one. There are also no drive places in some European cities as well, these were initially for pedestrian friendly reasons but have expanded to be smog free zones as well. If/ when it happens in the US, of course California will be first
