Why am I being routed on the freeway?

I started navigating from my home to a Saved Location. In my Avoidance Setting I have Major Highways set to Avoid. My Edge 830 incorrectly routes me onto a freeway aka Major Highway. I changed the Major Highways avoid setting with the same result.

This is disconcerting for a couple of reasons. 1) If I were unfamiliar with the area I may not realize that there are routes between here and there that do not require riding on the freeway and 2) it is ILLEGAL to ride on the freeway.

What good are the Avoidance settings?

Why does this device provide dangerous navigation?

    Plan your route with a route planning service (RideSithGPS/Komoot/Strava/etc) and put the route file on your device, then navigate that route.  Then you can make sure that you will avoid anything you don't want to ride on.  Routes generated by the device itself can be sub optimal.

    What location on what highway?

    It could be incorrect data in the map.

    If there was more information, I could check it.

    Yeah.  The Edge only knows what's in the map data loaded on it.  If you think about, there's one heck of a lot of roads, intersections, ramps, road type, direction, surface characterizations and other details encoded in the map data, so it's inevitable there will be errors.  

    Personally, like Wongataa, I always plan and create my rides on-line, often using multiple resources, sometimes using satellite and street views to verify, and download the courses to my device.  That way I know what I'm getting. 

    Always remember that navigation on the Edge "impels, but does not compel."

    Good call. I was exclusively using an OSM map that I downloaded from openstreetmap.org. When I additionally enabled the Garmin maps I got correct navigation.

    Not from openstreetmap.org.

    Maybe, you mean http://garmin.openstreetmap.nl/ ?

    There are different maps and they don't always work the same.

    The openfiets classifies cycleways as "highways" to get the devices to use them preferentially.
