In fact, in a way, basically everyone will use a baby stroller at some point in their life (at least as a passenger).

I personally never noticed this before becoming a parent, but there's a lot of spaces that are "almost" stroller friendly, but for some reason there is a small obstacle that would not be expensive to remove (if accounted for during planning). For example, a few steps that could easily be a ramp, blocks of flats with a lift that is accessible after ascending a few steps, even high shop entrances.

For me it's not a problem, because I can easily carry stroller with a baby inside up, but for most mothers I know this is usually a huge or unsurmountable obstacle.
