So lets suppose, you sold or traded in your old car and then bought a Tesla that it turns out that you don't like. What will you do then?
It's a classic silicon valley style move on their part: get out of the games you don't want to be in. In this case, the business of car dealerships not being the same as the business of car manufacturing.
Besides, the long play of Tesla is likely not in Tesla branded cars at all. They are slowly making the IBM move where they own and license the tech that other companies rely on.
The legal responsibility of autonomous vehicles and the long term warranty responsibilities of batteries as they decrease in capacity sounds like a terrible business to be in.
A, say, Ford "with Tesla tech" is likely worth substantially more in the mind of the consumer then one without. Pushing off the responsibility of the first point of contact is invaluable for a scaled business.
The bigger market than your own line of cars is to make the parts that all cars use.
It's the best powerplay they have access to in the market position they've formed.
Notably:
> We will accept your vehicle for return if the vehicle: Has an odometer mileage of less than 500 miles at the time of return;
> ...Is in new condition, without damage or abnormal wear and tear...
> To return the vehicle, you will need to deliver the vehicle (including all original equipment and any parts and accessories that came with the vehicle, including the mobile connector kit) to us at a Tesla Sales or Delivery Location (or other location that we agree to), and complete a vehicle inspection...
...but these terms describe a 1-day process for test-driven vehicles and 3-day process for not-test-driven vehicles, so it looks like they haven't updated the page yet with their new return policy.
Regardless, it looks like they're planning to just eat any costs from returned vehicles. They're probably gambling that the people serious enough to complete a purchase for one of their cars aren't likely to return it full of grease stains, french fry smell, and 900 miles later.
