While there is no reason why a registered disabled person shouldn't have a very nice car, I did a bit of a loose survey while walking around the Gardens and Ladder roads over the last couple of weeks.
I counted 26 different cars parked up with blue disabled badges around the area. They were almost exclusively Range Rovers, large white Audi's, 5 series BMW's and even one Porsche!
Life is either getting a bit better for disabled people in London (which would be great) or something is afoot.
Now here's a thing: if I'm reading this spreadsheet right, Haringey has the highest number of blue badges reported stolen (367) in 2017-8 in England.
