I can't find any place to search for "human generated" routes, that I would have some confidence that somebody created. (I can, on mobile, get some routes suggested - but in many cases, these end up being dangerous, and are not user generated from what I can tell).
I can create a new route, see my saved routes that I have made, but I can't seem to search for routes others have made.
My feature suggestion is: have a searchable set of routes, created by Strava athletes. Have a 'rating system' (5 stars perhaps), where people could rate the route, as well as a counter of how many people have rated it (and perhaps, how many times it has been used). There could also be a comment attached to rating/review, such that people can comment on any issues with the route (crosses a busy street, don't use at a certain time due to rush-hour traffic, etc.). This would give the ability to feel confident in the safety of a route.
