If you drive an expensive car you're probably a jerk, scientists say

Researchers from the University of Nevada, Las Vegas speculated that the expensive car owners "felt a sense of superiority over other road users" and were less able to empathize with lowly sidewalk-dwellers.

They came to this conclusion after asking volunteers to cross a sidewalk hundreds of times, filming and analyzing the responses by car drivers.

But the best predictor of whether a car would stop was its cost, researchers discovered. "Disengagement and a lower ability to interpret thoughts and feelings of others along with feelings of entitlement and narcissism may lead to a lack of empathy for pedestrians" among costly car owners, they theorized in the study.
