Apple will sell a few cars at very high profit margins. They will never be a big player. Their goal is to take the best, most profitable 2% of the market.
TL;DR: I do not see a car being profitable enough for it to be a long-term product for Apple.
The problem is the most profitable market varies by geographical region. In the US, it's full sized trucks and SUVs. In Europe, SUVs are the best selling as well; but they likely aren't the mammoth US ones but compact SUVs.
If they go for the supercar market, they have to overcome some strong brand loyalty and likely most buyers will be just the "I want one cause, well, I can afford it out of pocket money," which may not be enough to sustain a product line long term. I think it would be tough to recoup R&D costs to keep coming out with new models and teh play would simply be to showcase technology to sell to other manufacturers.
They will likely have the cars made under contract just like they do with phones and computers. Apple does not own factories. Apple outsources manufacturing and will do the same with cars.
I agree, developing their own production facilities would be too expensive and risky vs using a proven suppler such as Magna Steyr.
The switchover will be like when we went from film to digital cameras. After a long, slow ramp-up, the speed of the transition hit a tipping point and then it happened overnight.
I don't think that is an apt comparison. Digital made it easier for many people to take and enjoy photos - no more buying ilm, getting it processed only to find out you dind't get teh shots you wanted. EVs do not provide simila rbenefits and have some negatives that make them less desirable in consumer minds.
What is holding up the transition now is the price of batteries. There simply are not enough factories making batteries yet. This will change soon and many are under construcction.
Another challenge is charging. Until that is as convenient as gas, EVs will not become widely popular. The infrastructure problem just extend to roads, either. For locations where apartments are popular it is not easy to install a charger in a garage, assuming you have a garage and parking space, as there may not be electrical outlets readily available and metering capability to charge the person using the charger if one is available. Not an unsolvable issue but one that currently limits EV adoption, IMHO.
