It dismays me how often you read on MN - and hear irl - people who are shamed for being 'lazy' for driving a relatively short distance. There will often be a thoughtful person who asks "How do you know they don't have a disability or mobility problems?", only to be slapped down with 'no, they definitely don't have any disabilities' based on.... nothing more than a crass assumption from an onlooker.
I also remember the recent thread about car-free Center Parcs-style residential areas, along with many others. When 'reminded', people will respond that 'they' will 'do something' [probably wholly inadequate and threatening their independence] for disabled people; but by 'disabled people', they mean blue-badge-holding wheelchair-users. Even if you have to live with disabilities, you're still only 'allowed' to do so within the confines of what they (able-bodied people with no idea of your needs) deem necessary.
If you try to get on with things (not that you usually have much alternative) instead of sitting there whimpering helplessly, this will frequently be used against you as 'proof' that you aren't disabled at all.
As for disabilities where you may have 'bad days' and 'better days' - and you rely on harnessing the latter to be able to 'function' in society (e.g. being told that 'you've had a month to do something - just like everybody else', even though you may only have had four or five better days in that timeframe to fit everything in) - people are just itching to 'gotcha' you and shame you as a blatant fraud when they see you just about managing to achieve something on a rare day when everything just about comes together to enable you to do it.
