It's not a dig. But the absence of thoughts of wheelchairs in there highlights how even on these threads it's easy to revert to ableism.
Just in case anyone doubts - I am very much of the view that it if isn't mentioned, it isn't considered.
It's bad enough having to use a wheelchair in the first place without having some random cyclist tell you to fuck off as they shave your wheels going past on the "mixed use" footpath.
