As always it will take longer than we expect to get real "driverless" cars, but also be here before we really know it. A ford leader was saying ~5 years ago something along the lines of "we will be selling a car without a steering wheel in ~5 years". Yeah right. Even IF you had a full driverless car, why would you make it brick when something like the sensors break?
So it is easy to get hyped up on all the progress made, but who knows, maybe in 10 years there will be cars without steering wheels on the roads?
