I am surprised by the people who claim you can’t tell she’s disabled in the videos. The unevenness of her gait is obvious.
No, it isn't obvious, so I'm not in the least surprised that others haven't noticed it.
There is no uniform gait - people walk in different ways and Grey was not moving slowly, the video shows her making reasonable progress along the footpath. There's no evidence in the video that she was veering from side to side or unsteady. If (as has been claimed) she has mobility problems, then it's reasonable to assume she would have a walking aid and had been advised to use one.
Not every disability requires a walking aid, you know.
Yes, I think we know that, thanks. But the claim has been made that she has problems with her mobility, so my comment above applies. In addition, she was on her way to a supermarket (where she proceeded to go on to after she left the scene). As she was presumably intending to walk back after she'd done some shopping, it's surely even more likely that she would have a walking aid if she intended to carry a shopping bag as well. And any balance problems were not evident before or after she waved her arm and gestured at the cyclist, which must have required some force behind the gesture.
