I looked at his route on Google Maps.  He passed up a dedicated bike/pedestrian path linking side streets to ride on main roads that are far too risky/narrow for a cyclist to use when there are better options available.  Plus, there's no way in hell this fat fuck averaged 11 mph.  He drove and his average was probably slowed due to traffic/lights. His route had speed limits of 25 and 30, so waiting at a couple of lights would account for the average speed while driving.
