Nearly crowded off the road by Merc driver on Wednesday, waved at him annoyedly but not impolitely (didn't have time to bend the requisite number of fingers), he jammed on brakes & I ran into his nearside mirror. No damage either side, heated words exchanged, he drove off, I rode on. Had a witness, could have reported him; but when I looked at the pic I took when he got out of his car I found that he was walking in front of his number plate as I clicked the shutter button. Anyway, not worth the hassle.
