I'm also saying that cars are the only option in a vast majority of the land in the US. Park and ride spots (especially with EV charging) would be a great improvement for many of the cities for those of us coming from an area without a reasonable means to get there other than by car if buses and metros were available. The closest major city to me doesn't have a metro, nor a great bus schedule. I'm trying to no be a part of the problem, but cities have got to get it together.

Also you can't totally eliminate roads for cities mainly for deliveries via vans and trucks. The need for locksmiths, plumbers, electricians, and the like also need to be mobile to go to the problems as well.
