There will be accidents where wearing the seat belt is what leads to death. BUT, they are so very few compared to the vast majoity accidents where seat belts (and bags) will save lives.
In this case it seems he got flung from the car on the intial impact whereas as his passenger survived because they were wearing a belt. Whatever, he was a total prat for driving with out due regard to his own and his pasengers life and others in an environment that could have led to far worse carnage.
The sad thing is this kind of headlining stuff just adds fuel to the increasing distaste of those who consider we should be getting from A to B in less than 20mph in jazzed up milk floats Having just read AK350Z's write up on his J o'G to LE cycle trip - what was his most hazardous moment? - when an old biddy had no conception of speed she was doing and others around her that she nearly took Andy out by turning left in front of him - one of the cyclists worse scenarios. What speed was she doing - probably no more that 15mph, but again just an idiot driver who could have so easily killed Andy.
