We were traveling back from AZ to OR and started seeing "traffic" slowdowns reported on the highway. It showed 38MPH average. This seemed odd at night with no large amount of traffic or construction. It turned out that the waze users were Semi trucks going up a large steep hill, and this caused waze to think there was a traffic slowdown. Is there some way to get waze to know that the road isn't congested, but that the vehicle is just not capible of going up a long hill at speed?
