Other industries also exhibit this, like media.
And that is what differs an auto company from a Google. The next car sold still has significant capital investment.
I have never heard that. Car companies are mostly manufacturing, that is the major part of their organizations and what drives their decisions. They have big engineering teams, but they have way bigger teams working at factories. If you had a company just creating car designs and selling those to manufacturing companies it would be a tech company, but the current ones aren't.
When I visited our customer auto assembly plants the only actual manufacturing going on at was the frame and paint. The rest of the parts were shipped in from other manufacturing facilities.
The auto company did design the parts and send them to contract manufacturers, which is what I worked at. Again, I’m sure this depends on the vertical integration and supply chain relationship of each company, but I think there is less manufacturing than assembly going on.
