The review gave me the impression that the vehicle did not provide accurate (over a period of time) predictions of how much mileage was left. If that is the case, why should the vehicle logs be more accurate? If the car measures something wrong, the logs would reflect that.

Then, the car uses the GPS mileage data alongside numerous other inputs to update its cruising range estimate based on what it thinks the batteries' current state of charge is. As anyone who has ever used a laptop or a cell phone knows, that is a far-from-solved problem.
