People with disabilities such as those that require mobility aids also face such issues but you're only talking about "strollerability"?

Abled people often don't think of disability as something that could ever happen to them or their loved ones (unless it has), so it's easy for disability access to get mentally back-burnered. But abled people loooove to think about throwing their genes out into the world, so that becomes the hook.

In the article I noted, "Every investment in walkability is also an investment in rollability; wheelchair users are among those who benefit most when sidewalks become safer." And, of course, Strollerability, for people with kids." nobody is ignoring mobility aids, we are just adding to the story.
