Route calculation with bike paths

The route calculation web.locusmap.app for bikes used to take more bike paths into account.

Example: DE 93173 Wenzenbach to 93192 Wald.

There is a complete bike path between these towns.

If I use a touring, gravel, or road bike, I am guided entirely along the road.

A mountain bike, on the other hand, uses the bike path entirely.

This makes little sense, because I can also use forest paths with mountain bikes.

Touring and gravel bikes, however, would be better off on the bike path than on the road.
