I was thinking more about inane things like speed limits, jaywalking, archaic and outdated laws that have obsoleted themselves but remain on the books, stupid things like that, which everyone violates every day without a second thought.

For instance, there is an ordinance in the town I work in that it is illegal to back into a street parking spot. Why? No one knows, and it is rarely enforced, but technically can result in a non-trivial parking fine.
