Speed limit enforcement

I'm sure you've seen signs that look like this:

I don't know about you, but to me this seems sort of like overkill, as well as having a sort of surreal feel to the threat. Anyway, it instantly made me think of alternate signs that would probably be more effective.

Sniper enforcement was the first thing that came to mind; more menacing if they played the Unreal Tournament announcer saying "HEAD SHOT!" at random intervals (even if no one had been speeding).

(Also: I know it's a counterstrike image, but UT announcer quotes are applicable to all areas of life)

Some people have the opinion that "they would give anyone a badge and a gun these days"; why not show them how right they are by employing a T-Rex?

Ceiling Cat made the universe, so you damn well better be scared of speeding because he's watching you.... Always.

A Bubb Rubb sign probably wouldn't stop people from speeding, but it's for decoration; that's it, that's all.

Perhaps a Darth Vader sign could find new ways to motivate them.
