Well, it kinda makes sense. Apple are one of (if not the) the most desirable brands in the world, and they’re used to buying in knowledge when required. Their expertise always used to be software and the customer experience rather than hardware, so moving into EVs where it’s not about a beautiful engine or nuanced handling but rather more how simple and integrated the package is could work.
That said, it’s a million miles off if ever. Potentially a better avenue for them would be to supply the software that drives the car, both literally and figuratively. Imagine an interface for the entertainment/drive modes with the elegant simplicity that Apple are known for: that would be worth looking at.
