> It can be improved but mostly that just means commuter rail which still requires using a car for everything other than commuting, and usually people drive to the commuter rail station anyway.

Fun fact / example: My hometown started as a logging town next to train tracks, but grew outwards in one direction, so the train is now off towards the edge of town and it would take most residents around an hour to walk there. Just about everyone who takes the train drives there and uses its parking lot.
