I don't know exactly how the Sarte GPS-based road trains make driving safer, lower gas usage, or make travel more efficient, but it sure is fun to imagine all of the things that could go wrong! This seems like a much better idea if the lead car is somehow not controlled by a human.

One of the keys to the study is finding a way to make travel more efficient and lower gas usage without spending the treasury on putting sensors in roads, or creating an entirely new standard of equipment. Also, using a lead vehicle that could take control of the vehicles behind – cars, trucks or buses – makes Sartre much more flexible since it can travel on any highway.

Thanks, Dave.
