London Transport Blue Badge

London Transport has just launched a 'Blue Badge' scheme for those with 'invisible' disabilities, asking others to let them have a seat.

My autism makes me very unsettled when having to stand on a tube train or bus, and I am also rather unsteady on my feet, especially when standing 'still' (which in my case often means wobbling from side to side!

I wonder whether these badges work (They say words to the effect 'Please let me have a seat'.

Has anyone got one or applying for one? I notice on the website that it appears this facility is for Greater London Residents only, as if these are the only ones who travel by tube or bus with an 'invisible' disability.  I have to go to London several times a year so such a badge would be useful to me.  I am going to write to TfL to see what their rationale for this is (and the London Mayor too perhaps)
