It can't be admitted as evidence. The same idea that it could be used to prosecute could be twisted in future crimes to establish locations which could prove innocence falsly.

All you would have to do is let an accomplice drive your car to Vegas or Tahoe while you whack someone in LA, and then use the Onstar data to clear you.

Any Onstar data, short of a video establishing who is at the wheel with a time/date stamp would be reasonable doubt either way IMHO.

Not necessarily so. People who are traveling do many other things beyond just driving, like purchasing meals and renting lodging. If done with a credit card, all of this leaves a remarkably clear paper trail, often with signed credit card slips along the way, which provide additional evidence to verify that a particular person was driving a particular vehicle at a given time.

Also, if the only evidence of a vehicle's driver's location is GPS data, other information about where that person was and who had access to her vehicle could be introduced to support or refute the assumption that she was driving the vehicle.

Finally, on the issue of GPS itself, I have it on my vehicle and it is uncannily accurate, usually within about 50 feet. Government agencies also consistently use it when the want to establish the accurate locations of buildings and other facilities. For example, the Tennessee Valley Authority, for which I worked before retiring, used and uses GPS fixes to locate and identify each of its many buildings for Federal energy reporting purposes.

That's why they accompanied the GPS with a person following him.

Since this was apparently an installed device, merely finding it would allow the possibility of downloading the generated file and uploading it after modifications of the location data.

Not necessarily. Once in Vegas or Tahoe there would be records, and people who could confirm you were there.

Electronic records, credit card charges, phone calls, ATM activity, are already being used in courts to establish where someone was.
