I took a London black cab recently for a trip to the hospital, and the driver at one point overtook about 200 metres of stationary traffic, going around several "keep left" bollards, to go through the red light that the rest of the traffic was queuing for. The driver was in his 70s, so I'm not sure if he's just been doing it so long that he doesn't care about the rules any more, or if he was struggling with some kind of age-related brain degenaration. In his defence, I did get to the hospital well in advance of my appointment. It reminded me of the old Sega game Crazy Taxi.
