On a more positive note, I was with someone who was wheelchair bound
and the journey from Marylebone to Parliament Square was very
straightforward with the use of the ramps on the bus. In fact, we
reckon that they were having their first bus ride in nearly 30 years!

That's a shame, the first LFBs appeared in general service in London
about 10 years ago.
