I have always said that owners of expensive cars are less considerate drivers, and now a study has proved me right. The study showed that they are less likely to stop at a pedestrian crossing to allow someone to cross the road than drivers of less expensive cars – in fact, their likelihood to do so decreased by about 3% for every £800 increase in the vehicle's value. Previous studies have also shown that wealth is associated with greater self-regard and lower levels of fellow feeling. So next time an expensive sports car comes along while you are waiting at a pedestrian crossing, you can be sure that it won't stop.
