Great, so when a deer jumps into the middle of the highway the size of the ensuing pileup is twenty times larger. I don't particularly think we should use technology to push efficiency to the point where a mechanical failure, a material failure, or an unexpected object cause much larger scale catastrophes than exist today.
Why not aim for the same distance between cars and twenty times more safety instead?
