North end of Tottenham Court Road - 4 lanes of one-way traffic, some going left immediately into a side road, some going left at the next junction, some going straight on, some going right. Bendy buses going left from the right hand lane, bendy buses going straight on from the left hand lane, double-deckers going right from the left hand lane. Taxis diving left to a hotel to pick up rich fare. Pedestrians crossing. Bikes rlj'ing left right and centre. Somehow I managed to thread through all this brownian motion traffic every night, helped only by the fact that I've never found all 4 sets of traffic lights that pepper this stretch green at the same time, slowing everyone down just enough.
