Scientists have confirmed the more expensive your car is, the more likely you are to suffer a superiority complex.

A study done by the University of Nevada shows drivers of higher cost cars are less likely to give way at pedestrian crossings.

Researcher Courtney Coughenour told Mike Hosking they also looked into whether gender or race affected decisions.

"We did find that cars were less likely to yield to male pedestrians and non-white pedestrians, although our results did not reach statistical significance.'
