It is possible to add an option for users to sign up and make an account, if you want to get personalized information that is best suited for you. The system will recognize what you have already seen and knows what your preferences are. This way you only see places that are suitable for your needs and preferences and it is even easier to find places where you really want to be.
A fun extra option would be a button to generate a sort of surprise route. RLY generates a route for you with random places (when logged in, it could be based on personal preferences).
Same idea as above, only then a little less random, you can choose a random route from a subcategory
Longer routes (e.g. above 3 kilometres) could have an option to connect them to a bike.
