Tesla advertises EPA range which is a mix of city and highway driving with an average speed way below normal interstate highway speeds. I use the navigation all the time, even when I know the way, because it knows about traffic jams and so I can get a good range estimate for longer trips. It even gives you a round-trip estimate back to your starting point.
