It's an upgrade from my perspective. I paid $10K less than I would have paid for a 75D. But I take your point. It's not the best example. Nor are the other two I offered. But they're the best I can come up with, and I think they hint at the possibilities for software-customizable cars.

You don't think you're paying for the hardware? So you think Tesla takes a loss whenever it sells a car with Autopilot hardware for which the customers don't buy the software upgrade?

If they don't, then you're already paying for it. I think it was a mistake to do it like this, and it made all Model 3's more expensive than they could have been.

Yep, that’s rampant in the electronic test equipment industry. Keysight will sell you a $13k box, with $26k of hardware options to enable.

It’s the business model IBM basically pioneered that rocketed them to the top of the mainframe space.

It may be new in the world of consumer cars, but it’s not new under the sun.
