Sort of begs the question: what if you use the same driver often in a given city? I had a guy in Chicago...just got assigned him randomly one day, liked him, got his business card, and rarely used anyone else from that day onward.

Of course, it was still transactional - not an annual contract. Maybe that's the distinction? I suspect that the driver owned the vehicle and was not a W-2 employee of the limo company, but I'm not 100% certain.
