This is where Strava is interesting because of how fine grained the data is.

You can reasonably assume that a place frequented by road bikers is an acceptable surface for electric scooters, or wheelchairs (the surface only, not necessarily an appropriate setting).

A well worn path will show many walkers and runners, but almost no road bikers.

I'm sure there's all sorts of accurate inferences that can be made from the data.
