You can tell who's a fool by seeing if they thought Apple was going to make a car.
Apple was never going to make a car. Apple is a high profit, low risk company. Cars are inherently massive risk, no profit.
They will wait until cars become software, then they will move hard into it.
But think about it - 5000 iphones is about the same amount of metal to make a car. 1 plane can move around 5,000 iphones or 10,000 watches especially with their smaller and smaller packges (now without charger).
That's literally bricks of money being moved at a plane load at a time.
Now think cars, they need massive investment in the $10B range, they need to move these cars via boat ONLY and they need to store these cars at storage facilities.
On top of that they only make $5000-8000 per car, and then have to maintain their fleet.
There's no benefit.
You're right in that the traditional auto business is tough; low margin & high capex. However the key is the autonomy part, that's where it gets interesting.
