It would be interesting to know how the demographics of Jaguars and iPhones vs Androids match up. I wouldn't be surprised if that those in the market for high-cost cars are also more likely to be iPhone users, so maybe iPhones are a majority here.
Remembering the rules of distribution within categorical propositions I would be more likely to believe the reverse: iPhone users are more likely to be "in the market for high cost cars". However, that statement has so many economic and image related connotations, that extending it logically to a brand (JLR) that has image and reliability issues would seem to be a stretch.
(Referencing the article: I would seem to be in the techie category, with extensive higher education, so not surprisingly I own an android based system. However, when the author states "Both iPhone and Android people are affluent, educated, eager digital device consumers, and well-represented across the adult age spectrum up to 65" he lost my attention - what about the billions of cell phone users that are neither affluent nor educated?)
I would not be surprised if iPhone users overweigh wrt Tesla ownership, similarly Honda or Toyota ownership. But "overweigh"-ing only implies more ownership that would be expected by a random distribution, hence both iPhone and android both overweight with regard to higher education.
A survey would be nice, but believe me, if JLR's market research folks had determined that the majority of their prospective customers were iPhone users, AppleCarPlay would be a feature in the I-Pace, and I would be driving an "i-Pace"
