Defensive driving includes not speed-matching people in your blind-spot, and being mindful of merging cars, going so far as to move into an adjacent lane if the merging lane disappears. The cars need to consider this anyway. More thoughts on speed-matching the car in your blind-spot: there are many, many things that can go wrong, even if a car has omnidirectional visual information. If a tire blows, you have to compensate. I wonder how much sway-room a computer needs to retake-control/move the car off the road.
