A friend once cut someone off in San Francisco traffic by making an illegal left turn. At the next stoplight, the offended driver got out of his car, came forward & began stabbing my friend repeatedly until he finally said, “If you keep this up, you’re going to kill me.”

The attacker stopped & sped away. My friend managed to drive to the emergency room of a nearby hospital, but collapsed on the car’s hood as soon as he got out. His next memory is of waking in a hospital bed.
