See the video below -
I just found this very cool video about a Chinese concept for a bus.
From the YouTube description: "Tired of traffic jams and tail gas? The design of electric "straddling buses" lets cars drive underneath them, and can help reduce air pollution. Also known as land airbus, the new invention is less costly than subway systems."
|A Screen Capture From The Video|
It can carry over 1000 passengers and travel up to 60 Kilometers an hour or around 40 mile per hour and costs only 16% of building a subway.
Powered by electricity the bus could replace as many as 40 conventional buses potentially saving 800 tons of fuel annually.
A VERY COOL idea!!
