I liked Gallagher’s idea of having a gun that would shoot these arrows with flags on the end that say, “Stupid!”, everytime you see someone do something stupid on the road.
Then after somebody accumulates about a dozen of these “Stupid!” flags, the cop pulls them over.
I remember that but cop pulled him over and give him a ticket for being an a-hole! It’s a bit not but stupid speech to text gets me again...
Paintball guns... (water soluble, of course...)
