Can you elaborate on "instantly crash" at all? I've crashed travelling in excess of 70mph a number of times on road and racetrack and as far as I can tell I'm still alive.
There's a difference between crashing and carrying on e.g. sliding down a track and coming to a dead stop (like the bike did inside that car).

The problem with stopping instantly is that your organs carry on going, so for example one of the things that happens is your heart carries on moving inside your chest and your aorta (major blood vessel suplpying blood to the heart) is literally ripped out from your heart. It's quite short and not designed to move very far.
If you slide down the track or are thrown from your vehicle (or manage to jump off) then you have a much better chance.

There was an accident on the A350 a few months ago when several bikers were going down to Poole. A volvo pulled out from a layby.
The first bike hit the bonnet, flew over and broke his arm. The second biker hit the car in the middle and just stopped dead and he was killed. The body cannot cope with massive deceleration.

There are 2 main problems I have with this thread.
One is along the lines of what Beemerman said.

I can't comment on the sentence as I don't possess the necessary knowledge or experience to do so.
We have very few facts.
There are differences in every case and relying on sensational media reports and entertainment programs is dangerous.
It's possible the guys attitude was taken into account when sentencing and also many other factors.
We have virtually no facts at all on this thread about cases, only opinions and judgments from a flimsy media base.

The other issue is that I agree with a lot of posters (like JP) that this largely comes down to individual responsibiity.
Sure the police, council and other motorists have a part to play but mainly it's down to us.
Whipping up sentiment in a anti-establishment direction and making everyone feel they are victimised and persecuted is not particularly helpful towards encouraging personal responsibility.

I'm not advocating that everyone rides their bikes flat-out whenever they can, but that the judicial system keep things in perspective
I agree with Beemerman.
We don't know the circumstances or the guys attitude or the details of other cases.
So you don't have a good basis for saying it's not in perspective.
