LOL, "f**k 'em" is precisely what my friend/carer says too. I should definitely start listening and disregarding the idiots. The worst bit with our local car park is that there is only one set of lifts, in one corner of the car park, leaving the rest of it fed only by the stairs (on alternate levels) or the long walk around. More than once I've just stopped along the way and waited for him to drive down to me. Some people just don't think about how difficult it is for people with mobility problems to get around. It's definitely tough when you "look ok". You throw up, you must be drunk. You fall over, you must be drunk. You pass out, you must be drunk.... and yet, the ambulance crews are perpetually being called out to drunks that people think are really ill - how does that work? Regarding "accessories", I've actually seen post-minor-keyhole-surgery guides recommend that people take out a walking stick to clue people in that they're feeling fragile, for precisely these reasons.
