[Kraftwerk]

Forty years after tearing the street car tracks up in order to use buses, Geneva, Switzerland has now replaced their tram lines at great expense. The main reason is energy: move more mass with less friction. Electricity instead of oil. They are nicer to ride and have less stigma than the bus.
Actually if people respect them ie. stay the heck out of the way, they out perform any mass transit in every respect.

Sorry to hear about the dump truck driver though.
