Does racingbike avoid unpaved surfaces?

Hi - can you let me know if the “racingbike” vehicle profile avoids unpaved surfaces please? It says in the documentation that it “prefers” roads, but is it possible that it could it route people on gravel paths for example that are unsuitable for a road/racing bike?

Yes, racingbike avoids unpaved surfaces.

but is it possible that it could it route people on gravel paths for example that are unsuitable for a road/racing bike?

It is still possible. Those routes are not excluded entirely. The speed is assumed to be very low and so these roads are almost always avoided.

Thanks for the clarification, much appreciated. So, presumably it would be correct to say that this option avoids unpaved surfaces unless the route would involve a long detour?
