Speeding

What is the point in speeding? Have you not heard the advert-"There's a 30mp limit for a reason". The advert (http://www.youtube.com/watch?v=4kQwdaKCvBc) is very extreme in order to have an impact on those who speed and make people think twice before they do it. I think people may do it for an adrenalin rush and possible to show off to friends. Also, when young people race is very dangerous, I suppose it's their age that makes them do certain things but that doesn't make it acceptable, especially when innocent people could get seriously hurt. I know people who speed and they really couldn't care less. This is an example of bad behaviour, and in my opinion fairly ignorant individuals which we have within society.
