Well, first of all, no one said that ALL cars must be automated. But for the people that want it, good for them, it would make the roads more safe to drive on.
There was a story on Beyond 2000 way back in the day about a company that was working on 18-Wheeler trucks that would follow eachother. There only needed to be one driver for any length of trucks. They even had the system working with up to five trucks at the same time. That way you can have two drivers swap out in the lead truck and drive until the trucks start running out of gas. And if the following trucks don't need room for driver's sleeping quarters, they can have larger gas tanks. The lead truck would just have to have an oversized cab for two drivers, large gas tank, and enough sleeping facilities for both of them.
Bring it on!
