What does reading the key tell the service advisor?

Recently bought the car and took it in to the service department to have them fill in some paint chips, polish the headlights and replace the rubber molding at the top of the windshield.

When I picked up the car, I was chatting with the service advisor and he mentioned that by reading the 'key,' he downloads the car's mileage, fuel level, and can even tell whether I have been wearing my seatbelt. This got me wondering: what else is the key logging about my car? Does it record top speed, throttle opening, rpm/time, traction control or anti-lock activation, boost pressure, etc?

Seems like even if one were to remove a tune/tuner, BMW could prove one was used by referencing such evidence. Does anyone have knowledge of what these cars are recording/reporting about us?
