If all cars were self-driven and there was a system that allowed them to exchange information, negotiate decisions, etc with all cars in proximity, that would be the ultimate vision safety-wise. I expect that we&#x27;ll live to see that day. Removing the human factor would be removing the biggest problem.<p>On the other hand, making this mandatory would also be the wet-dream of most governments. In the name of safety, they could have access to so much information... Just knowing how many passengers the car is carrying, what&#x27;s the weight of each passenger, and, of course, a history of the coordinates, would open insane possibilities, not all of them good.
