Sure. If you then take personal responsibility for every accident even when going at or below the speed limit, I could quite live with this. "Personal responsibility" of course means making good for any and all damage you caused, something which you are typically quite unable to do.

The fact that people still have "accidents" and that these "accidents" are ruled "accidents" and not "willfully crashing their 2 tons of metal into something" suggests that people are not ready to take responsibility for their actions and that they cannot be trusted, even with the current speed limits already in place.
