Ah true. Still a complete failure on his part.
On a much less serious note: Mayor of london said no more bendy busses, didn't happen for a while and Top gear continued to harass him about it and I'm not too sure how that one went down in the end...
Point being, it was a simple idea, order up some normal busses, sell the old ones. They seem to be taxed enough to support that or putting the old ones back into service.
