Bastard. That bit is a nightmare, it helps to go more into a primary position so there's no room to squeeze through like that but that driver is a cunt for doing it.
Awful bit of road that. Even if you ride primary there is always some twat that will try it on if there's even the tiniest gap in oncoming traffic. Stupid thing is, if they can just control their impatience for 5 seconds, there is plenty of space for a safe overtake as soon you round the corner.
This happened to me on my commute this morning (apologies for language):
