Probably very expensive.
But wasn't there some rumor already some time ago, that apple wanted to make a car?
But cars are a different ballpark, than consumer electronics. So they are likely cautious to not burn their money there.
Again, I'm not arguing that Apple might not make a number of other design decisions that could lead to the car costing much more than that. I'm just saying that the cost of the Vision Pro sensors won't be the reason.
And to be clear: I don't think the Vision Pro implies that Apple would needlessly increase the price of a hypothetical car. The Vision Pro is as expensive as it is not because of some perceived "Apple Tax" but because Apple had a vision (ahem) of what they wanted to build, and it was at the very limits of technical possibility, and they chose to release it now (2024) instead of five years from now. For comparison, the original iPad, which was anticipated to cost a thousand dollars, shipped at half that price.
Ah. And then there is Tesla ditching an external temperature sensor and relying on weather info for the GPS location to save a few bucks. I think the automotive industry works on a completely different standard when talking about parts and margins.
