This looks cool, but please add translations, I don't speak Dutch(?). :) One question: are you using OpenCycleMap? If not, it would be worth adding as it highlights a lot of the safer routes, such as Eurovelo and local bikeways.
Yes it's Dutch, will add translations soon. I like the OpenCycleMap suggestion. I am indeed looking for ways to highlight safe or nice roads by using OCM or maybe Strava segment data.
