in germany scooters are not allowed to use trunk roads. Kurviger has support for “not using speed roads” which seems to does the same.
My question would be: It seems quite easy to add your own VehicleFlagEncoder. I don’t want to create a full navigation-solution but hope for more and more software to support this kind of routing, since it isn’t currently available in any navigation-solution for iOS/Android that I would be aware of. Would you be interested in having more FlagEncoders in Core, or do you want to stick with the very basic ones?
Tbh: I don’t know about the legal situation in other countries. I think that rule is the same for all EU-Countries. Scooters are limited to drive 45km/h and trunk roads require the vehicle to drive 80km/h minimun.
This is the issue :). In Germany “Mofas” also differ from 45 km/h vehicles, because they are sometimes allowed to use bicycle lanes. In other countries, 50 ccm scooters are not common, because the legal situation is different and everyone just drives 125+ ccm. I also think that the speed limits vary greatly between different countries for scooters. In some countries any motorcycle/scooter form is forbidden on highways (e.g., south east asia).
I think as a first step it would be fine to have a German Scooter profile :).
