The technology behind is really awesome. But it's also interesting to note that common modern transportation is being brought up as part of a modern city, and to my mind it's a pity relatively young cities don't get better at that. It doesn't take a rocket scientist to noticed the gridlock, and see that good public transport really is the key to all the road congestion issues, and ultimately making our predecessors life easier with less time and stress in getting from point A to B in the future, which self driven cars won't help resolve. If anyone has ever traveled in Switzerland would understand what a smooth and precise rail and bus system can do.
