Gallagher had predicted this back in the 1970s. Issue every driver a dart gun, and darts with a attached "stupid" flag. If someone cuts you off in traffic, you shoot their car with a stupid dart. If a cop sees a car with more than five stupid darts on the trunk, said driver will be pulled over and ticketed for being an idiot.
Instead of 5 stupid flags, they could look for one Obama bumper sticker.
