• Respondents also scored high on the "psychopathy and sadism" scale, but the study was only for cars. Truck and motorcycle owners, the study suggests, might score even worse.

A new study by Western University in Ontario says that if you've got a car with a modified exhaust system, odds are you're a guy and probably also psychotic and sadistic. Slapping a Cherry Bomb glasspack on your Monte Carlo doesn't (necessarily) mean you're a Ted Bundy–level psycho, but the data someone points to a personality that enjoys inflicting unpleasantness on others.
