My wife works for UPenn and her department has a vehicle that is for company business. There is a pretty strict format where it is signed out, purpose stated, mileage recorded, and job # or grant # for billing purposes.
I hear about this once in awhile when stuff goes awry...like the interior of the vehicle being caked in mud the day that the van was to pick up some foriegn dignitaries at the airport. Another similar issue occurred with the PA Secretary of Agriculure visiting needing a quick morning detailer to work some magic.
Unless the driver was in full time possession of the ride, there should be an internal paper trail that cannot likely be favorable for Georgia.
Marshall's point about policy and enforcement is a strong one too. Maybe there were other staffers out that night with players in company cars that didn't have issues? Is that any different in terms of deviation from policy? Did they get reprimanded or written up? Logic says that people probably try to use the company car (AND GAS) as much as possible.....or they can get away with.
We may never know the actual settlement amounts, but tens of millions seems to make sense. A real sad situation all around.
