How far in the future are we talking? It seems unlikely that we’ll manage to rebuild our infrastructure so that cars are no longer required in less than two generations.
Secondly, this is a timeframe of about 30 years. Making dedicated lanes for PEV's is not that hard. (I bet the urban planners in big cities are already making plans, considering how much of the delivery services have already switched to PEV's.)
I agree that we can greatly reduce our reliance on cars in the next thirty years, but I'm certain that cars will still be a significant fraction of our transportation by then. Not everyone lives in a city and many cities have too low density to be practical for public transport and small electric vehicles alone. Changing that takes a lot of time.
