I'm not saying that there are no bad drivers ( there are plenty) but the amount of times I have watched a YouTube bicycle close miss or collision video and thought why are you cycling up the inside of moving vehicles or blindly following a cycle lane into hell cycling flat out into a situation I saw comes miles back , then from personnel experience I've watched cyclists running red lights jumping onto pavements to turn left at red traffic lights and then not looking when they jump back onto roads, cycling up the inside of HGV's, Buses and other vehicles, cycling up the inside of vehicles clearly indicating left ,no lights and black clothing whilst wearing head phones, onto oncoming traffic ( wrong side of road) shopping bags on both ends of the handle bars and something I saw the other day a Black African on a black bike dressed in black cycling the wrong way down a high speed unlit dual carriage way at 3 am in the morning in the fast lane. Add this to all the other humans using different methods of transport with no brain or consideration for anything else but them selves even if if puts them in danger, phone zombies, drunks, junkies plus those making errors ( we all do it) and there is no surprise people get hurt, Speaking as a HGV driver all you can do is try to be the best you can and protect others against them selves and in the case of cycling protect yourself by obeying road rules, wearing high viz clothing , good lights and good safety equipment.
