Would you want a car that drives itself

i would like to have a car that drives itself because i could sleep while driving. i think that a car driving it's self would be a great method of driving. we could sleep and be refreshed for whatever event they have next. i could talk and pay attention to the person i am talking to while the car proceeds to the destination i have it going to. it did occur to me that the car may break down and cost a lot of money, but i think its worth it.
