After a drive I would like to give feedback on the navigation. I would log in to a web site, find my route, view on a map and then be able to click and say "Here, Waze said 'At the roundabout, take the third exit' but it should have said 'At the roundabout, take the third exit and then keep left'". I have many cases where there is room for minor improvement like this - but too minor to be done while driving.
