Profitability for something as big as starting up a new car company is pretty much always a delayed gratification thing. Research and development, plus tooling up and building out manufacturing capacity are all enormous front-end expenditures. Nobody, including Apple is going to turn a profit on the first cars to roll off the assembly line, unless they sell for a few billion apiece. That's just not how it works.
Tesla's approach has been wise, I think. By starting with high-end models, they obliterate preconceptions about electric cars and make them something desirable. Then they work their way down to more affordable price-points with models that are still desirable and are made with expensive engineering refined and by this point actually made more affordable. So as model 3s get ready to hit the moderately-priced market, no one is looking at them as overly expensive, under-powered, mostly impractical environmental social statements. Instead, they hit a pre-prder sales record because they're cool, and not an expensive, personally inconvenient political statement.
Who knows what Apple will do? My guess is that they'll take some lessons from Tesla, and whatever car they produce, it won't be an ugly little bubble like the now-ubiquitous MotorTrend joke of a mockup.
More often than not, automotive company startup gratification is delayed forever. A lot of bleached bones out there, even those of companies that seemed to have everything going for them (e.g., Kaiser). Other venerable car companies failed not because they weren't making good products but because they were located too far from the crucial supply chains and consequently were unable to compete on price (e.g., Studebaker). This is why I believe it is almost certain that if Apple does this thing, their manufacturing will be outsourced to Asian companies with existing assembly lines. I sure don't see them going down the same path as Tesla. Whether their approach has been wise only time will tell. We know now only that they've been unable to deliver on promises and are seeing some major reliability issues with their existing fleet. The aura will wear off if they can't fix those problems pretty quickly if only because their competitors are coming on line in a hurry.
