Exclude highway from scooter route

There is a parameter avoid[features]=controlledAccessHighway, which prevents highway usage. If this parameter is used, then scooters are not allowed to use highways even if allowHighway is set to true. In this case, with scooter[allowHighway]=true and avoid[features]=controlledAccessHighway, the scooter is not allowed on the highway and the calculation returns the fastest route that does not go through a highway. If no route is possible that avoids the highway, then the calculation returns a route that makes minimal use of the highway along with a notice (with notice code violatedAvoidControlledAccessHighway).
