Yup, I’ve heard of all of them.
I can see why the no backing up. I, for one, am out of control in reverse - I can’t be the only one.
I do not for the life of me understand the “no barefoot” one. I always drive in bare feet and don’t feel like my driving is impaired in the slightest.
Eating while driving takes your attention away from the road (not that that stops me, but that is the reasoning). And, of course, under that reasoning they should also ban cell phones, radios, smoking, drinking (non-alcoholic, of course), and whatever else you can think of.
I always thought the leeway was 10 miles over the limit. (well, since I drive 15-20 miles over it’s a moot point for me :))
