If the cars you see in your rearview mirror tailgating you always seem to be flashy models, it is not coincidence. Owners of more expensive vehicles really are less considerate drivers, a study has found.
People with expensive cars are less likely to stop at zebra crossings — possibly, researchers speculate, because they tend to be more self-absorbed and less capable of empathy.
After observing nearly 500 drivers, psychologists discovered that the value of their car was the best predictor of whether they would stop.
The odds of them allowing a pedestrian to cross — as they are required to do by law — decreased by about 3 per cent for every £800 increase in how much their vehicle was worth.
