Concerning the OPs statement that this is an effort wasting " Billions " : I am quite certain that the funds being spent are the monies of corporations not our tax dollars . It would be the shareholders who might be upset by how the assets of the company are being spent and they can express any disagreement in many ways including voting out the Board of Directors .

I am probably one of the most skeptical people on the planet. But, I am surprised that so many people think that developing a self driving car is a pipe dream. In my opinion, it's only a matter of time before they will be readily available. It just needs some basic engineering, and these cars will be the safest cars on the road.
