..and "moving slowly"!
I'm always amazed how oblivious some of the mid lane hoggers are. Mind you, the girl in the Vectra I saw on the M25 recently had a 'phone on her shoulder, a pen in one hand and a note pad in the other so she was clearly far too busy to worry about lane discipline :-)
Trouble is, if the pillock moves over on you it's your insurance that will have to pay at best. Tempting though it is, sensible drivers stick to overtaking on the right.
