Was in my last 400 yds of my journey home. I was overtaking two parked cars, but was only going slow as there is a junction about 50 yards ahead on the left and the road surface is shocking. As i overtook the first car, a Xsara Picasso began to overtake me. There was a car parked on the opposite side, and an oncoming driver also tried to squeeze through the gap. My available space narrowed until the car that was overtaking me clipped my right handlebar with his wingmirror. I was going about 5mph max by this time, but the impact turned my front wheel, i hit the parked car inside me and came off. I wasn't hurt, apart from a jarred right wrist/thumb. The bike (Wisper 905se city) was ok apart from a displaced chain. The driver that hit me lives 4 doors up from me. He'd stopped to make sure I was ok, but realised he was in the wrong and was very sheepish. He also admitted he'd been distracted by his sister waving at him from across the road! I'll see what happens to the thumb/wrist before i decide whether to report anything tomorrow. Feeling a bit ropey now though.
