I remember telling a close friend of mines about autonomous cars (cars that have their own brain to drive itself). He was like a car will never be able to drive itself without a human driver behind the wheel. This was back in 2013. I remember when California made it law for autonomous vehicles to drive throughout the state by 2015 again this was in 2013. I as of now realize that there is a difference between self-driving cars and autonomous cars. I heard about this Vehicle to Vehicle communication back in 2016 that the Department of Transportation wants to see put in place. By the year 2043 it is planned that all cars on the road will have to be autonomous.
