True.. But point is it can only go where the track goes. I for one don't want a computer deciding where my car goes without my involvement, and even more so, don't want everyone else around me in other cars thinking they don't need to even watch the road anymore. And I work in IT, leverage new technologies as much as possible. But cars move too fast to rely on sensors and computers.
