You probably knew this, but research has confirmed that people are more likely to act aggressively with others while in their car than they are in person. Thirty per cent admitted to swearing at strangers while driving, compared with 12 per cent who do face-to-face. More than a quarter (26%) shout at others while driving, compared with just 12% doing that in person. The study also found a third of drivers (33%) have beeped their horn aggressively; 11% said they had deliberately tailgated another vehicle. Among the top 10 excuses for driving aggression are the belief the other person probably cannot hear you, and feeling protected inside the car.
