The point was about, or at least could be made, beyond just cycling.

Replace "Accessible Cycling" with "Accessible form of transport that does not endanger other people not using that form." Whether that's bicycles or wheelchairs or scooters, etc.

So what, you want to intentionally exclude people from the benefits of biking? Why? How is that better than making biking accessible to a wide range of people, like some countries already do?
