True, but they'll happily take 10 horrendous accidents over 1100 minor bumps if the bumps cost them a thousand each and the bad accidents cost them a hundred thousand each. Our incentives are different. We would rather have many tiny incidents (up to a limit) than a few life threatening incidents. Therefore, while an insurance company would happily put into place a process that turns a small number of drivers into maniacs and everyone else into placid sheep they'd take it. Not that they are, and it sounds unlikely that such a process can even exist, but it's important to know that our incentives aren't aligned.
