text: First of all they have bulit in GBS so they wouldn't get completely lost like a human can. If there tech is advance enough they could avoid danger more effectively since a computer can react faster than human. There would be a decrease in mortality rate on the road because there wouldn't be as much danger paying attention somewhere else like being on you phone since you aren't the one driving. The amount of money you'd spend on gas would decrease since it would always drive the most cost saving speed.( while staying in bounds of the speed limit of course) You could be more productive with your days since you would be spending less time driving the car.
