Hi there! I drive an Energica electric motorcycle and having the option to avoid highways in an EV route planner is absolutely fantastic!

My request is to be able to plan more "fun" routes for motorcycle drivers. Other apps like TomTom Go Ride and Calimoto offer things like "Thrill" routes (which are often routes with many long-winding curves) or "Sightseeing" routes.

I have no idea what kind of algorithms these sorts of apps use or how they would score routes other than on their curvature.

I also realize that I'm in a very small niche user group and this feature likely has very little business value, but I figured I'd put it out there ;)
