> People feel that they paid double – which was actually not true, but perception is reality It was true. The heating wires in the seats were already installed and the consumer paid for them and owned them. I remember in the olden days some compiler vendors added a fee to "unlock" floating point code support. That was never popular (I never did such with my compilers.)
1. Those who purchase the heated seats cover the cost of all of these heating wires. So they are paying much more than the raw cost (but presumably less than if their cars needed a separate / modified production line).
2. The manufacturer is paying these costs as a "marketing fee" hoping that they will recoup their investment (and more) when people pay for this feature.
I agree that this model feels wrong but after thinking about it I have convinced myself that this can be a good thing. It allows those who what the feature to pay for it, without removing the option for a cheaper model for those who don't want or can't afford the feature.
I wrote a blog post about this a while back: https://kevincox.ca/2023/05/14/ethics-of-locked-hardware/
