Imagine being able to sleep while your car drives you to your work-place or driving you to your holiday-destination? I think this would be super awesome, and you wouldn't need to take long frustrating car tests to get a license, etc.
Quoted from http://news.bbc.co.uk/1/hi/magazine/6906162.stm:
"But there are other less obvious benefits. Children could be driven to school."
Actually, that'll be a benefit, the car drives your kids to school, but instead the child says "take me to the mall"

lol. Okay, on a serious note, this future development would be fantastic! You'd be able to read a book, talk on the phone, and allow your car to do everything for you - maybe you could attach your caravan to your car, then tell your car what to do, get all the family in the caravan, have some food, watch some telly, the life hey? Lol. Do you think this could come true? Maybe they could make technology very smart, be able to understand human language - finally, those fiction films like doctor who are finally going to come true! lol
