they still need someone on board

i was more thinking of light rail anyway... i hate buses, and trams have all but vanished from so many cities even though they are awesome... automatic ones would be the best urban transport IMO

and small scale intercity transport... that's another thing that has disappeared or gotten extremely absurdly expensive in the last couple decades

i like the pace of rail transport... and the straighter paths, and teh lack of up and down bumping
