My guess is that they just plug in a standard 12 or 14 mph and leave it at that. Maybe if we report excessive travel times as "problems" they will get the idea and raise the average speed.... or maybe prompt for average cruising speed and adjust times based on that.
FYI, Google Maps typically overestimates traveling time for driving as well.
