Well, the last brown trouser moment I had cycling as a result of a motor vehicle was caused by a Porsche 911. I was on a single track road with hedges and could hear something very loud coming towards me so was already on the brakes - he came round the corner, hit his brakes and immediately locked his wheels up and missed me by inches as he skidded past, half on the road and half on the verge. Doesn't matter what sort of brakes you have, they don't improve visibility round corners or improve traction on wet, muddy country lanes.
This incident was near Midlem (where I think the tw@t lives, I've seen it parked there since), so watch out Reiver, it's in the area. It's red and has a TO55ERS type number plate.
