A few years ago, I thought hat for self driving car would need to redesign the road and put those sensors on the road for the car to navigate, boy! am I wrong on my thought. Now the driving cars just equip with many sensors and cameras, and the help of GPS it can navigate it way around. Taking the google car for example, does close to 100,000 miles with 2 accident that weren’t its fault, some other driver were hitting it. I think that’s a big accomplishment.

But now, more and more, and almost if not all car manufacturer have a prototype of self driving car. In fact it’s available now for sale to drive on the road. Especially in Japan. In the US, I think laws has compliance has to be set up first.
