Former Top Gear Stig Ben Collins may be right about autonomous cars. He recently gave a Tv interview where he expresses a rather pessimistic and worrisome view of the future of self-driving vehicles.

He also expresses concerns that machines can and will go wrong, and there's also the threat of hacking too. Check out the interview in the video below:
