A lot of your post wreaks of 'citation needed' but I'll choose this one.

>Many cites engage in "zero tolerance traffic enforcement" programs. This is where they patrol a single stretch of road and stop every single person who is even 1mph above the limit.

Searching this all I find is Virginia where over 80 is an automatic reckless driving, but the highest speed limit in the state is actually 70. I've never heard of anyone being pulled over for 1mph over the limit.
