Red lights will still mean stop. Green lights will still mean go. And white lights will tell human drivers to simply follow the car in front of them."

The white phase concept rests on the fact that it is possible for AVs to communicate wirelessly with both each other and the computer controlling the traffic signal. When enough AVs are approaching the intersection, this would activate the white light.
