On the other hand, I don't think Tesla ever said it wouldn't advertise (it just doesn't really have to advertise in the traditional sense, up to now), and I think the only idea behind the "no discount" rule is that you can't negotiate a price with your "dealer" (the "showroom/inventory adjustments" are for everyone, as are the "reverse discounts" - aligning the price of not yet delivered cars to those of new cars, if there has been a price reduction, or former options now included in base configuration - certainly nothing wrong with that!)
Yeah, my point really is that many of those things that may well have made sense at one point - been genius, even - have outlived their usefulness IMO and are causing more trouble than they are worth these days. All the fiddling with "Showroom Adjustments" and taking free Supercharging off and then bringing it back and off again, and all these stunts to keep the quarterly demand going up... This is the time when it would make sense to move to a more mature, more sustainable business model in these regards.
If you actively choose not to advertise (they do advertise inventory, but in a small way only) and not to offer discounts (not even discount campaigns) publicly, then you really limit your options on pushing sales - and then you have to start resorting to an increasing amount of gimmicks and stunts to make it work. And that will at some point become counter-productive IMO, probably already has in some ways. They could get these results and more with a more traditional approach at this stage IMO.
