See what Rimac did, it is a good example that starting a luxury sports car company and be successful is possible nowadays, and talking from the ignorance it seems to me easier than the past. If that is what apple wants or needs is a different story.
What Rimac did was partner with big automotive OEMs for research joint ventures and sell a tiny number of cars and a relatively large amount of battery and drivetrain tech to other OEMs. Difficult to imagine anything less like Apple's business model than that.
They might position themselves as an aspirational brand outside the US, and by keeping retail prices close to the same as in the US, no matter the local purchasing power, I can see how they can be perceived as an upscale brand in some markets.
So now, instead of buying things twice because the one was shit, I just buy Apple. I don’t buy “the iPhone”. I buy “iPhone”. It could be 99% more expensive, it’s still less than buying things twice.
