This won't even be necessary as the self driving cars will have vastly superior reaction time when compared to humans. Especially if the cars are electric and thus have almost instant power to the wheels.

Especially if you use tricks like radar underneath the car in front of you so you can react to what the car one car ahead of you does etc.

Also a lot of the highway traffic jams are caused by too small distance between the cars. A self driving car should be much more efficient in keeping enough distance between the cars to keep up the flow.
