I fantasize a virtually car free world with a system of train pods replacing most roads. Some roads would be turned into foot and bike paths. My world might allow small electric golf carts. Also horses might be more commonly used for transportation because they are quiet. It would be great; walk to a track, push a button, wait for a pod and off you go. I could travel from a spot a few blocks away all the way to California without need to drive or share my space with strangers. And I could hop off anywhere in between, look at whatever, and then wait a bit and hop another pod to resume my travels.
