What's your top speed?

... the design of bendy bus used in London was really intended for continental (particularly German) cities with large ring roads with a dedicated uninterrupted bike lane. Anyone who has ever watched one trying and failing to make the turn out of Gower St, for instance, and blocking the traffic for several phases of the lights knows that TfL have been over-ambitious in the routes they've given the bendy buses.

I think this is point.
