I assume that someone has done an analysis of how the sensors will interact when there are many self-driving cars on the road?
Because many of the primary sensors are active (radar, lidar), will they work when they're surrounded by 50 other cars also blasting out the same signals?
When 50 other cars are nearby actively communicating with each other about the road conditions that they each see, only a representative subset of those cars need to correctly identify road conditions and report them to the entire group as a road-conditions map. Cars in the group validate the observations and risk-factors reported by other cars. Then each car independently makes its driving decisions based on this shared-data based on its relative position in the group.
In this way, being surrounded by hundreds of other cars is a plus, and leads to more data by which to determine safe self-driving behavior.
