GUN lobbyists like to repeat the quote often attributed to American writer Robert Heinlein, that "an armed society is a polite society". But this is certainly not true for motorists.
A survey of 2400 drivers carried out by David Hemenway and his colleagues at the Harvard School of Public Health shows that motorists who carry guns in their cars are far more likely to indulge in road rage - driving aggressively or making obscene gestures - than motorists without guns.
"Our findings indicate that the people driving around with guns in their cars are not among the most responsible and best-behaved people on the road," says Vriniotis. "In the interests of injury and violence prevention, it probably makes more sense to tighten rather than relax restrictions on gun carrying in motor vehicles." (New Scientist)
That'll be the day, when America's gun laws make sense.
