Reborn in DBZ as a Human?

A young man was slowly crossing the street. He made sure to look both ways before crossing the street, he had read too many novels where truck-Kun suddenly appeared. Just as it seemed safe he started crossing the street. That's when he heard a loud roaring sound as Mercedes sped around the corner and hit him full force. He flew back 3 feet and when he hit the ground he was already dead. I got out of the car as fast as I could, I was the one driving the Mercedes, and I had just killed this young man.
