The Transition from Horses

Trevithicks steam carriage, world’s first vehicle designed for carrying passengers.

"A steam carriage intended for passengers was built in England in 1803 by Richard Trevithick. A replica of it was built recently and has been touring Europe. It was basically a carriage stuck on top of a crude steam tractor, the passengers were a good height above the ground. It was also a commercial failure but had the distinction of being the first self powered land vehicle in the world designed to carry passengers." source
