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
LOL, I like that. With your premission I'd modify it just a bit:
Part 135/charter pilot = taxi driver
Fractional pilot = Limo driver
Corporate/owner pilot: Small bizjet = chauffer; Large bizjet = butler @ Downton Abbey.
Cargo pilot = Commercial Truck/Lorry driver
Regional/LCC airline pilot = abused bus driver
Real (legacy) airline pilot = airborne professional
BA, AF, LH, DAL (or equivalent) Captain = Nobility
International (legacy) airline captain = SKY GOD
