TFL ignore bikers again

I've just received a TFL survey for cycle planning in London.

In the main body of the survey it asks you to list your use of various methods of transport such as car, bus, overground, underground, DLR, but no mention or choice for motorcycles or scooters. Discrimination yet again?
