If you let someone drive your vehicle without taking all reasonable measures to ensure that they are legally entitled to do so (licence, insurance), you are liable to prosecution as a result. Car hire companies generally will ask to see your driving licence to head off this liability. Doesn't mean that they have any busines forwarding it to the credit agency, though.
