I think the blog is unfair on Gaz, and I think the BBC programme was also unfair on Gaz.
I see no reason for the cabby to be going into the Bus lane at that point, especially when the main traffic lane was free, and regardless of the position of Gaz (which was the correct position to take, with the speed being travelled, the motor traffic ahead, and the traffic lights ahead).
Just like alot of other blogs out there, it is just someone spewing crap, they are welcome to put out their viewpoint, but singling out people is a bit much.
