Manners please

with regards to 'riding wide' - what do people do when a car (usually minicab) gets pissed off with you and comes really close up behind, half overtakes and pushes you into the gutter?

any techniques for avoiding this?

They wouldn't be able to overtake you if you were riding wide enough. That's the point. They'd have to run into your back wheel to do anything to you and basically.. that's pretty fuckin' unlikely unless they are completely psycho in which case I'd feel justified in killing them and their children and their parents and their dog.
