No, you're not getting it. Geo-fence is the backstop safety mechanism for SuperCruise, not the primary mechanism. They don't need to update geo-fence to account for changes to "ground truth." The whole point of the geo-fence is to confirm sensor data and assist in identifying anamolous situations like accidents and construction. If sensor data doesn't match "truth" then the self-driving system can engage safety mechanisms, engage additional processing, or disable self-driving as appropriate.
