When I was in University I did a research paper for a module called Emerging Technologies. One of the suggested topics (everyone ignores suggested topics as well) was automotive tech, which interested me straight off but I focused down on safety research. Some of the stuff I heard back from car companies and research labs was mind-blowing, it's just starting to appear now in stuff like this Mercedes. Not sure if they've started getting it together or shelved it, but there was a plan for having adaptive controls based on the cars essentially becoming a large network and being able to respond to changes through the entire 'pack' of cars.

Give it a few years, I think some of the tech they'll start trickling down from luxury cars to everyday will start making a massive difference in terms of road safety and getting the car to do more of the work.
