By the way, anecdotal evidence suggested that people in wheelchairs
travel free on TfL buses. But none of the drivers (nor one inspector)

Ideas anyone?

"Eligible disabled" people qualify for a Freedom Pass if they live in
London. These passes are paid for by the London boroughs and give the
holders free travel on most public transport services in London.
