Primary position

Ok, I've had enough of being driven at and verbally abused by drivers telling me to 'get in the bike lane'.
Drivers on the whole don't know about primary position.
Please can someone educate the masses before this gets out of hand.
:(

It depends. I've heard worrying cases from some on these here boards advocating riding in primary just for the sakes of it- something I would not push- as it just causes avoidable aggro.
