You don't think it'd be nice to sit back, relax, read a book or newspaper, eat, watch a movie, play a game, surf the 'Net, or even sleep while your car gets you where you need to go? Without the need for a big windshield and other peculiarities of being driver-oriented, car interiors can become much more comfortable while the cars themselves become more aerodynamic.
You could send your kids to school (or wherever) on their own, in their own little one-person cars, with no worry about whether they get to where they're going, and no need for you to take them. It sounds fantastic to me. You could even send your car to the store, order the groceries on-line and have them loaded in the car and come back to your house without you having to go.
The possibilities of automated autonomous vehicles are endless. The funny thing is that the popular science fiction vision of such systems required them to run on rails or inside tubes or some other kind of confined/confining system which also excluded other means of transport. But now we have sensor and processing capabilities that allow vehicles to travel automatically on standard roads alongside human-driven cars, on roads where people can also walk or ride bikes or whatever. It doesn't require a big, expensive infrastructure like a train/monorail/whatever -- just a flat, hard surface. Which we've already got all over the place.
There will always be human-driven cars around, for sport. Horses are still being ridden; cars will still be driven. But cars won't be a part of everybody's daily lives, like horses aren't now.
