- Every car would have a bar-code on it's roof.
- Several police units would patrol the town about 50 feet above traffic. (This is the 21st century. Where ARE our flying cars, anyway?)
- When an asshole drives like an asshole, the flying police unit would video the prick then zap the asshole with a bar-code scanner.
- After being zapped by the scanner, a red light on the asshole's dashboard would go on alerting said asshole that he's busted.
- Said asshole would have 30 seconds to pull over and wait for a ground traffic cop to arrive to deal with his dumb ass.
(Can you tell that traffic is pissing me off, lately?)
