I don’t really understand the calls for people to sell the Teslas they already own. Those vehicles are already purchased and paid for (even loans and leases; the money paid on those does not go to Tesla, who has already been paid in full). To the extent that they are covered by warranty, they actually cost Tesla money the more they are driven. And those lucky people with free Supercharger access are costing Tesla even more.
Further, to sell a Tesla requires someone else to buy it; it doesn’t remove it from existence or use. Unless you’re suggesting that people scrap their vehicles, which seems incredibly irresponsible environmentally.
