Now about the chauffer stuff ..... I don't mean to disparage chauffers; a good one is worth his weight in gold, especially if you own a Rolls. It's just that I prefer to be a pilot.
Funny you should use the analogy of chauffeurs to describe corporate pilots. I use this analogy to explain to non-aviation folks what the main sections of commercial flying are.
Corporate pilot = airborne chauffeur
Part 135/charter pilot = airborne taxi driver
Airline pilot = airborne bus driver
