A perfect world
I was driving with my son to our weekly wargaming night yesterday, and I saw several instances of idiot drivers. And I mean turning right from the middle lane, diving across two lanes of highway to hit an exit, driving on the emergency lane and the list goes on.
I was reminded by all of this typical Memphis driving by an idea of a friend many years ago. Drivers go to the police station, and for $50 you pick up three serialized "darts." Instead of a sharp point, it has a bulb of special cement that only the police have the solvent for it. If an idiot driver does something unsafe in front of you, you merely drive up next to him and hit the bad driver with a dart.
After the driver has his 3rd dart removed, he gets a $50 ticket for being an asshole.
