A facility to move a column of vehicles down a road without it degenrating into a game of bumper cars. Something along the lines of being able to tell a vehicle to follow a road until it gets to point x. Whilst following the road it wouldn't need detailed movement orders that takes every bend and turn into account like it does now. Also the driver would automatically skirt round obstacles like parked vehicles rather than plowing into them and then reversing, thus slamming into the following vehicle etc etc.
