Though a rarely brought up fact when discussing self-driving vehicles, planes have been on the right track for the last few decades with autopilot. The automotive industry should take some lessons learned from the government regulatory structure, and avionic makers, and build a system capable of high capacity traffic with extremely low fatality rates.

Issues that we deal with when driving an automobile are amplified 100x when in the cockpit of an aircraft. Traffic is nearly impossible to spot during the day time without someone like an air traffic controller (ATC) telling you about it. Managing a plane in inclement weather is an effort in bravery and extraordinary situational decision making. Crashes, though statistically unlikely to be fatal, can have extreme consequences for both passengers an innocent by-standers. All-in-all, the experience of flying is just plain difficult. There are dozens of controls to handle at any given moment, and even the distractions are amplified (ever tried writing something down while driving? It happens in planes all the time)

So how did we overcome these issues? Regulations and technology. Just looking at the traffic issue, there are rules for which alititude to fly at for which direction and type of flight you are, rules for entering high traffic areas by verifying you have communicated intentions first, rules for what equipment your plane has to have before entering specific high traffic areas, and strict expectations that pilots will be able to control their aircraft to the best of their ability. There is plenty of redundancy in the system as well.

I would venture to say that landing a plane is much more demanding than driving a car, even in the most severe driving conditions, yet we trust autopilots to set the plane down in even the most severe 0 visibility scenarios (http://www.youtube.com/watch?v=7BUA3EwKpVM). The technology in vehicles is beginning to make sense to implement in the same way we have it present in airplanes right now, but I would love to see the regulatory structure begin to step up and build a reasonable, redundant, and safe system for driving an driver-less car. Then I can see the world you are describing.
