I would like to have these features on my navigation application:
Prefer unpaved / gravel roads.
Give me a route that takes 2 hours with motorcycle to my target even if it is only 30 km away.
Mark drive through and non drive through roads separately on map (~at intersections) during navigation so I can reroute my trip on the fly.
Mark unpaved / gravel roads on map.
Yes, I like to drive unpaved roads as long (drive through) route as possible with my enduro motorcycle!
