I got 22 (With an odometer which is not exactly right, but close neough for government work) drivnig back from Boston to VA going from 60-110 depending on what the radar detector said. Driving to Caharlotte this wekend wih the new GPS unit which measures distance within 5 meters, so I might be able to get a more accuract reading.
