2009-07-20 - Black Cab hit and run

On this I think you are wrong.
Black Cabs, by their very nature, are inherently a lot more dangerous than other vehicles.
Every other vehicle is going to a set destination. The driver knows where he is going - some more than others - and will direct his attention to getting to his destination.

Black cabs on the other hand, are being directed by passengers, often on a whim, (whilst directing their attention to being conversational, chirpy, claiming to know the Krays or being casually racist) and when they are not the driver's attention is focussed on getting the next fare. They do u-turns, sudden turns, go for gaps as they see them - the works. And often without so much as a look in the mirror, let alone the indicators.

I'm with BlueQuinn on this one.
