I tried fixing this in https://www.openstreetmap.org/changeset/178532060. The issue seems to be that OsmAnd directs drivers to stick to the 2 right lanes, which are bound for Mission Boulevard, even when drivers want to stick with I-880. The issue seems to be that the navigation logic thinks drivers want to slide right, so they do not enter onto the HOV lane, even though there are 3 regular, straightaway lanes.

Since the 2 right lanes do not yet have right-turn indication before this point, I modified the turn:lane property so that all the lanes are set to "none". I expect that this should improve navigation. I will check later once this change is propagated.
