Great call out. They sell cars to capture future service revenue. This is why you can't sell EVs effectively with a dealership model. The product threatens their survival.

Printer manufactures sell printers to capture future ink sales revenue. This isn't unique here.

While probably true, I would love to see the traditional car dealership business model go away. The only reason anymore to have a dealer is a place to test drive, and you do not need a huge lot full of cars for that.

Traditional brands sell many more SKUs than Tesla. It is likely they will need a large lot just to have all the variations in SKUs available for test drive. Tesla isn't particularly good at their so-called "demo drive" actually. Last time I tried to test drive both AWD and RWD variations of the same model but they couldn't do that. Needless to say I didn't buy a Tesla.
