It is The dreaded Bendy Bus. Many cyclists really dislike these, and they have been blamed for an increase of injuries in London. Quite apart from the real danger, it is quite obvious that the articulated nature of them leads to a reduction in subjective safety for cyclists, and we already know how important that is.
Over here, buses rarely get all that close to cyclists as we're on the cycle path (red) while the buses are on the roads, with the speed bumps to try to keep them and the other motor vehicles under control.
Note also the way the road rises up a little at the position of the crossing for pedestrians (and cyclists just off the right of the photo). Just enough to give drivers a hint that they should slow down at this location, but without causing cyclists (on the cycle path) any problem at all.
Getting "knocked down by a bus" is not all that uncommon where buses are mixed in with cyclists. Large vehicles don't ever really mix very happily with bicycles, and that's one reason why I have never thought much of shared bicycle / bus lanes. The only time I've ever had to ride in a bus lane in the Netherlands, it had been converted into a bike lane because of road works.
