Re: I think the cyclist is at fault.
Especially when you watch cars ahead manoeuvring to ‘close the gate’ - sometimes quite late & aggressively; so that the poor sod on the bike suddenly as nowhere to go..
On the other hand; why are there no ‘Bikers THINK Car’ (maybe the ‘Car’ is an overstatement). Don’t bloody well hide in my blind spot(s) - or tail gate me; etc etc - I suspect that the car drivers who ‘close the gate’ are just pee’d off with some of the more stupid bikers
