Are there any free navigation apps that allows me to specify my speed on different road types? I want to, as far as it is reasonable, avoid to drive on certain road types. A good way to accomplish that is to set the speed to an artificially low value. Co-Pilot offers this functionality but it is not free and I would use it very rarely (a few times a year).
Edit: Another example of navigation software that allowed the user to specify the speed was the desktop version of Route 66.
