I have to totally disagree Biggles.
In this world of social media there is a dangerous culture of one up mans ship. Do anything to get you head on youTube. It is leading to particularly young males to try and defy physics as you say too often and as we all know physics will always win in the end.
There was a case where a young lad was killed here at Maitland show last year trying to break a world long distance for a motorcycle jump (on a 125 I think).
The media proclaimed it a tragedy. It wasn't, it was pre ordained. If one keeps trying to set records evetually you will go too far and somettimes pay a terrible price as this young man did. He was only 17 or 18 and everyone consoled themselves by saying he died doing what he loved. I wonder in the cold light of day if those who supported him and basked in the glory of his achievements have ever re-thought their role in his demise. A life well lived is worth so much more than a cheap stunt to grab a headline.
But hey never being one to stand in the way of another individuals rights even if it is to do something stupid, as long as my taxes don't have to pick the medical bills knock your self out. Pardon the pun.
As motorcyclist we all take a risk that the rest of the population don't every time we jump on a bike. But it is a calculated risk with well established safety protocols and most of us do whatever we can to minimise the chance of an accident.
I have seen the case in point first hand and it is fairly harmless, I even prepared a car for the daughters boyfriend to enter into the smash up derby at the same event. (sadly the attempt on his life failed) but we do need to be careful of what we encourage people to do. Particularly young boned headed Gen Y's. (not that there would be many reading this forum!!)
