The Transit Elevated Bus (TEB) is powered by electricity and can carry passengers above two lanes of traffic while cars drive underneath it. The 22 metre long, 7.8 metre wide and 4.8 metre high bus trundled along a 300 metre stretch of road in the city of Qinhuangdao, Hebei province, at an excruciatingly slow speed for its inaugural test run, but the finished version should hit speeds of 40 mph.

That thing is huge.
