Mmmm, I think I might have a young nut-job on my commute. Two v poor overtakes in three days from the same young guy in a white BMW in the Toft area. This morning, 500 metres later, I pass him as he is queuing to get out of a junction and he is laughing when he sees me come past. I resist the temptation to stop and chat/re-position his wing mirror. If it happens again, I'll adopt a different strategy.
I might even stick a camera back on my bike
