Boris Johnson, yes him, was Mayor from 2008 to 2016. He was something of a mascot for the Olympics, but did not really do much for London.
Part of his legacy is the Boris bike.

It was a bicycle hire scheme devised by… well, not Mr Johnson. Actually, his predecessor Ken Livingstone started it, but Boris took it on when it looked like it was going to be a success.
We don’t see Boris bikes around these days, but assume they are still on the go. Certainly other systems are. You see bikes littered on the pavements and roads wherever you go.
I was talking yesterday with someone I know who has worked for TfL for very many years, and for a long time on the buses, so has personal experiences. They were not shedding any tears about the Boris Bus removal, though it is old news, and had more tales to relate (but I won’t put them here).
They did say that the heating/cooling was adequate, but that the bus companies chose not to switch it on, to save money. In the winter it could be cold, but in the summer it could reach over 40C and people really were fainting.
Having an opening window defeats the heating and cooling system, and it makes no sense to me that they would pay millions for new windows rather than just switch on the heating/cooling and make sure it was up to the job.
