Not against this idea, but it seems like the real solution is better government service for the available public toilets for areas that don't already have it.

Not against this idea, but it seems like the real solution is better government service for the available public toilets for areas that don't already have it. In my area there is a simple map layer that shows all of the available public bathrooms. Other than being a convenience for the public, it's partly an essential service for people with crohn's syndrome, IBS or other medical issues that lead to urgent toileting requirements. This seems like an inexpensive way of better utilising what is already there - this is something that should be done in addition to any new toilet-services.
