Is is done at step 3 most of the time. But Tesla mess up (they shouldn't, but they do) on occasion and it doesn't happen until later. That's when a post turns up here from an angry buyer. The fault here is a bi diffuse, Tesla take some blame (for messing up removing it), the seller (for mis-representation, or ignorance), and the buyer (for perhaps not doing their homework). Basically, Tesla need to fix their systems so that a car that goes through their hands never leaves it mis-configured.
I would like to see the documentation when the car leaves Tesla’s hands to see if any blame goes past Tesla.
