Assuming you have no disability, have you ever parked in a Disabled Parking spot

[Ms. Toad]

95. If they don't have a tag that's fine.

Your comment was addressed it to people without visible disabilities, not people without tags. Being able bodied enough to "dash" is not necessarily an indicator that the person does not have a disability you can't see.

For example, having an identified parking spot adjacent a door may be the only way for a person with memory impairment to find his or her car. That particular disability might not impair the ability to "dash" - but being able to park the car in a clearly identified location may make the difference between being self-sufficient and being dependent on others.

I had vertigo for a year recently - I didn't have a parking tag, but because of the particular kind of vertigo I had, dashing was much easier for me than walking slowly. I was most at risk for falling when I stopped moving.

I'm not an expert on all disabilities that are invisible, but I know enough people with invisible disabilities to know how much harder their lives are because people heap scorn on them based on the assumption they are faking it. Scowls are bad enough - but many are also verbally attacked, or their cars damaged, because it is assumed that they are taking spaces that others need.
