My thought here is that the app should optimize time and distance. Last night we were in familiar territory. Waze picked a route that was 8.1 miles but 22 minutes, whereas the usual route is 9.5 miles and 12 minutes. If the user selects "shortest" and the app is just ranking distances without any other adjustments (picks 8.1 20 minutes over 8.3 15 minutes), that seems silly. Meanwhile, we are switching over to "fastest"! :)
