I think a credible threat of serious punishment would go a long way. Unfortunately the justice system and police have completely abdicated any responsibility they might have there.

Maybe instead of attempting to find fault we should roll the dice in accordance with the speed vs lethality tables whenever a driver hits something with another person in it.

Sorry Jim, we're going to have to kill you today. The simulation says you drove right into the maw of a redwood chipper.

That's basically what it feels like using a mode of transportation that carries a high risk of death in a collision.
