So how much of a tool did I feel like! Flittering, to the front, at slower then walking pass, i nudged a mirror of a little Astra. First time in 3 years of ridding - I felt like a complete twit. The space was smaller then i thought, and was paying too much to the car on my left as flittering through. Knock. break lever into mirror. No damage, I looked, moved in front on him, and put my hand out to say sorry - he checked and waved back as if to say ok. So I felt like a bit tool. Is this part of filltering that happens occasionally ??What do you do when you bump a mirror ?? Hopefully first time, and last time I do that!
