VeryLittleGravitas I don't want free parking. If I go to town I expect to pay, regardless of where I live or how I get there. Unless I walk (which is not an option, even though I CAN walk).
OP My friend has MS, and all of the above mods, its shit unfair in life that she has it, its a massive struggle and I wouldn't wish it on anyone, it severely limites her choice in many many ways, and the ease of her day to day life... she wouldn't not mind paying for a parking space with her blue badge. She has little income, all benefits, mod car etc., her ILLNESS and disability IS her hardship, a small parking fee would not add to it.
I am in no way anti-disability at all. I am not being offensive or highly emotive, haven't resorted to sarcasm or guilt trips, and I'd thank you not to do the same. Its simply my opinion based on people I know and experience of that.
IF a parking fee for an individual blue badge holder would mean that they cannot possible afford to pay it or go into town, then in certain cases an opt out scheme would be perfectly valid... but not free parking for all blue badge holders.
