Routing issue with motorcar=destination

Hello,

I have a issue with ORS direction.

In an area with all road tagged access=customer, I would like to allow the use of certain roads only when it’s the destination of the itinerary, so the route would only take the main roads (it’s a large camping site).
I though I could use motorcar=destination, but it doesn’t seems to be taken into account. I can’t really use access=destination, because I think the access=customer is an information more important to people on OSM and it should not be removed.

So I edited my own ORS instance and edited the CarFlagEncoder.java with overriding tthe getSpeed() and setSpeed() when I encounter a motorcar=destination tag to set speed to like 2km/h but this also doesn’t work… I followed the use of the speed all along to the VehiculeFlagEncoder.java handleWayTags() to ensure the speed was not erased, so I don’t understand what is wrong, is speed not used in directions ?

Can anyone give me a pointer how to tackle this issue ?

Thank you very much,

Regards,

Antonin
