It sounds a bit like you would like to reserve the privilege of parking in disabled parking but don’t want to be identified by the blue badge as someone disabled. Sorry, but that’s just not something that the system should be designed to cater for. You either accept the badge and the privilege or you don’t, demanding that anyone must be able to park in disabled parking without a badge because they might secretly be disabled but not want to signal it seems beyond absurd.
