A WANING tolerance of other drivers and drivers who tailgate even at the speed limit are the main triggers for road rage, according to a Fleetcare national survey of 760 drivers. Women are particularly vexed by people who don’t give a courtesy wave when they’re allowed into a new lane, with 40 per cent more women than men believing this to be particularly annoying. Men, on the other hand, rate a slow take-off at traffic lights and failing to drive in the left-hand lane as more provocative behaviours, with 75 per cent more men than women supporting this. Men and women were equally annoyed when other drivers cut them off on the road, agreeing that this was one of the most irritating driving behaviours.
