"Proposed by Shenzhen Hashi Future Parking Equipment Co., Ltd, the model looks like a subway or light-rail train bestriding the road. It is 4-4.5 m high with two levels: passengers board on the upper level while other vehicles lower than 2 m can go through under. Powered by electricity and solar energy, the bus can speed up to 60 km/h carrying 1200-1400 passengers at a time without blocking other vehicles’ way."
Definitely an idea worth exploring to reduce congestion. Just don't call it socialized transportation please.
