The rage epidemic: is our modern world fuelling aggression?

After the video of Peter Abbott screaming road-rage abuse through a car window went viral, we ask what's behind the fury so many feel - and express

Last week a video showing 60-year-old Peter Abbott screaming abuse at TV producer Samantha Isaacs gained a viral audience, after Abbott was found guilty at Poole magistrates court of using threatening words or behaviour to cause alarm, distress or fear of violence".

In the phone-filmed video, Abbott is seen snarling and shouting as he presses his face up against Isaacs' car window. He looks as if he's channelling the Harry Enfield character Angry Frank, so cartoonishly aggressive are his contorted facial expressions and confrontational behaviour. Not only did he hammer on Isaacs' car but he also called her a slag" and a whore".
