Probably not "test" vehicles...just company driven vehicles.

The company does road testing on all models. I live a few miles from the GM proving grounds, and the cars are common here, usually in groups. Notice the Michigan plates, with the m in the center - manufacturer's plate. I have friends that have driven company cars coast to coast, as part of their job. The passenger's seat is usually full of instrumentation stuff, recording everything the car does. Unless there is a factory nearby, I doubt they are company employees running errands.
