You know, I’ve had a similar thought to what you’ve offered here. It’s always been a tongue in cheek observation, but because cars are so safe, people literally take their safety for granted driving them. If cars were less safe, people might take the responsibility of driving more seriously.

Make it so, if you get in an accident, it chops a foot off. So not life ending, but certainly life altering. People drive knowing “I’ll be fine,” and then they look at a text, daydream, all that. If you knew, every time you got in the car, you risked losing a foot, you’d take that shit seriously.
