That requirement is quite common in the "branded chauffeur" space though... Take the drivers that Emirates send when you fly business - They're never employed by Emirates (either employees or subcontractors of the cab company that has the Emirates deal for that airport), and yet the requirements are very strict: Black E or S class, less than 3 years old, magazines and water bottles etc.
