I wont bore you with the details except to say the usual non-overtake routine which means pulling along side and then giving me the squeeze as we reach a junction. Not sure why he did it. You can't really average a greater speed than a bike on the back lanes in The City and indeed only 10 seconds later he was held up by an oncoming vehicle so I went past on the left. Maybe he didn't like my assertive style. Maybe he's was just a cockwomble. Who knows? I didnt retaliate but it did spoil my ride, which is something I usually manage to avoid. Never mind, suppose its off my chest now and I'll try to be more relaxed on the way home.
