Speed kills........fact
If you actually look at the (official) figures, fatal accidents caused by exceeding the speed limit are actually fewer in number than deaths from falling down the stairs.
If it were possible to strip out the deaths caused by 'idiot driving at double the speed limit or more because they think they're Lewis Hamilton they discover they're not because they're suddenly decelerated by a tree', there would be remarkably few deaths in the '34 in a 30 zone/85 in a 70' category.
The biggest cause of road death is people not paying attention.
Before anyone goes all emotional on me and tells me I'm wrong, go google the statistics (you'll end up on the national archive site) then look at mortality stats by cause then think for yourself.
Disclaimer: I'm not saying that road deaths aren't tragic, it's just that if it happens to you, you've been statistically very unlucky, been driving like a bell end, or a passenger in teh car of someone else driving like a bell end.
