Because this Country's roads turn its users into utter bell-ends.
Donk mentioned earlier that cyclists wouldn't deliberately put themselves in danger, yet I do see road users doing this all the time; putting themselves in more danger just to prove a point.
I dont think some cyclists new to it do see themselves in danger
I think and its only my opinion that a lot of the folks on here are seasoned in their use of the roads both as cyclists and drivers, as such they see the danger from both sides , however to some degree cycling profficiency has gone out the window its a case of bob in halford buy a helmet and away you go ,the helmet publicity of it will save your life has just made them **** invincible
you couldnt do that on a motorbike and have absolutely no road awareness whatsoever but buy a bike and anyone driving miss daisy can quietly meander along the road till they get hit by a large hardbody object
Of course this is tragic and TBH motorists should drive with consideration that the folk riding bimbling along on their new transportation method it might make sense to educate both parties not just blame one particular set of road users right off the bat
edit, motorbike comment above of course theres the 16-18 yo subset who thrash the bollocks off their 50cc bikes till they meet some kind of demise or take someone else out
