> How much value can Apple and Microsoft extract from you over the lifetime of a single car.
Probably less than Toyota has extracted from me in my lifetime already.
Cars are lower margin, but they are expensive in absolute dollars, and their purchase almost always involves leverage. A $35,000 car will typically earn the manufacture $3-7k in direct profits, the financing arm gets ~$1800, the dealership gets ~$600 (plus profits from extended warranties, service, etc). There's still a ton of money to be made in automobile manufacturing.
And that's for an average car (actually, below average, the median new car price is nearly $40k). Vehicles like Porsches or an F-150s have insanely high margins. Porsche has the highest margins in the industry (50% for the 911) by a comfortable amount and Ford reports the percentage of F-150s sold for over $50k in their annual reports, and have for years, because it's the most critical aspect of their bottom line.
Tech companies benefit from having really dispersed revenue streams: they make a few dollars off of billions of people while car companies make thousands of dollars off of a few million people.
