Chrysler turbine car was awesome but ran hotter than hell, the turbine semis were awesome also people probably know nothing of these projects. I think Jay Leno has one of the cars, or at least he had a show where he drove one. Last time I knew there were only 2-3 left. The semis I'm not sure about. One of the biggest problems was in braking, there was no way to shut them down very fast. Correct me if I'm wrong.
