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.
You can use your brakes to slow down to where you can then engine brake, you just don’t want to use them for miles all the way down a mountain.
Once you’re under ~50 and you shift down to second, your engine does the work. It will keep the car slower. Maybe you need to tap on the normal brakes here and there, that’s fine, but you shouldn’t have to keep them pressed the entire time.
