I read about Mercedes-Benz having an autonomous car, this is great. If anyone were to do it first, it would be Google. Benz got it to travel from one city to another and will be out in 7 years.
They have the automatic break lock sense thing, which is pretty good for people who sleep behind the wheel or distracted.
But as for google, imagine these cars become the norm, then whats the social aspect of having a car is just for premium social status.
