Do you think it has anything to do with the dealer aspect of traditional car sales? For instance with legacy manufacturers the dealers are buying the car from the manufacturer as the middle man. So, the dealer probably wants to clean up the cars as much as possible in order to re-sell the car to a customer. They want the experience to be great so that customers return to their specific dealership (Sals Ford), instead of going right down the road to Jim's Ford. With Tesla the delivery centers have no skin in the game, they are just responsible for handing off the broken product that they were sent from the manufacturer.
