The barely-discernable oval track in the middle of the shot is the Honda Proving Center. From Wikipedia: Honda Proving Center of California (HPCC) is a test track used primarily for testing Honda and Acura automobiles. Motorcycles are also tested there. HPCC is located near Cantil, California, in Kern County. Security is tight, and pilots flying near the track have reported seeing cars immediately heading for cover as they got close to the facility. HPCC has a 7.5 mile oval track, as well as a five-mile winding road course.
