Well there's also the marketing aspect of the initial rollout price. If Rivian announced their trucks to be over 6 figures, 99% of the people will write them off and never look at them ever again. Just because a brand new Model 3 SR+ is being sold 10k above msrp doesn't mean Tesla should just priced them as such or else you can lose the plot kind of thing (and we see that Tesla is being criticized a lot by rising prices to levels beyond affordable. .Or they have to price the product right. How come they sell it for $75k to preorders while on ebay you pay $135k to get the same product. Why give all that value away for free? Not saying supply+demand curve will intersect at $135k but clearly $75k is too cheap, especially if cost to produce is too high.
This is why every company (except Lucid) tries to generate eye balls by announcing fairytale prices.
