that impatient driver isn't paying your bills if something goes wrong.

Whenever you feel anxious about an impatient driver behind you on the road, just remember that they're not going to pay your hospital bills, they're not going to pay for the damages to your car, they're certainly not going to buy you a new car, and they're not going to care about what happens to you as long as they get to where they need to be when they want to get there. So, the next time somebody honks at you when you don't go as soon as the light turned green, or you don't turn on red because you're making sure that there's no oncoming traffic, or you're not driving 20 miles per hour over the speed limit, just remember that they don't care about you, so you need to care about yourself at the end of the day.
