My kid’s just finished the classroom part of driver education and it prompted a discussion of crazy things we’ve seen other drivers do.
The craziest thing I saw, many years ago now, was I came up behind a guy driving a Ford Ranger pickup and could see through his rear window that he was doing tricep extensions with a dumbbell in his right hand. I was more surprised as I passed to see he was shaving with an electric razor in his left hand. I don’t really know how he was steering.
Kiddo said they were told personal grooming was the fourth leading cause of accidents.
Flip a car while streetracing on a narrow three-lane highway in the middle of the city, in moderate traffic that was moving 70 km/h ish at most. Amazingly they didn’t take anyone else out.
I called 911. They redirected the call to the police station. After I described the incident, I could feel the officer’s eyeroll through the phone. It was odd to realize that something so extreme for me was literally just another day for them.
Edited to add:
An old co-worker liked telling the story of how he was rear-ended on a very busy city highway. The other driver was a young woman who stepped out the car all distraught and said “I’m so sorry, I didn’t see you, I was putting on my makeup!” My coworker was ready to wave off the incident because there was basically no damage to any car but he changed his mind as soon as he heard that.
