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.
I had to pull off the road a bit and almost into the ditch on the highway to avoid someone who misjudged his passing distance and was still using my lane.
I signaled in the hopes he would see it and not zig to my zag.
He passed right in with the car he was passing, I edged the ditch a bit and then we all continue on our way.
I was a ways down the road before the chemical dump and realization. Had to pull over, of course.
