It seemed like the authors couldn't make up their minds about what type of automobiles we'd be using. There was the multi-section model that drove the whole family downtown and then separated into parts. There was the gigantic RV car that would carry the whole family around the country, even up steep mountains with elevators. Then there were the the gas turbines, jets, atomic, and electric antigravitic models.
The rocket powered transporters were interesting. This whole program wasn't really about the automobile. It was about the highways on which the automobiles would travel. The one theme throughout was that the vehicles would be automatically controlled. I liked that part of it. I'm no longer interested in driving for pleasure and using a car as a toy on the road. I'd much rather be a passenger in an automatically controlled vehicle. There wasn't much mention of busses or trains for passengers.
Having a highway passing in front of the Sphinx in Egypt was funny.
