Apple will never build cars. Each dollar of car revenue will hurt their margins. It doesn't matter how lux the car is or the target market, it isn't going to happen.
Tesla isn't going to be able to hold their margins, either.
It's going to be more like Nvidia - Nvidia captures all of the margin in the servers - with some going to Intel or AMD - and SuperMicro, Lenovo, HPE, etc. eke out their existence on the low value chassis.
