So. Freakin'. Cool.
The Superbus, a Dutch invention with a top speed of 155 miles per hour, is a 50-foot long hybrid between a bus and a train. It's also electric, which is an added bonus.
I'd say the Superbus is probably ahead of its time, but it's still wicked. Although it gets best results on a dedicated lane of its own, the Superbus could run on any highway, and might offer a much cheaper alternative to inter-city high-speed rail transit.
