This is the stupidest and most pointless idea I've ever heard here. Who writes up stuff like that? I'd like to get paid grant money doing that. I can bullshit about things I've no clue about plenty. I even have a penis, which is like +5 skill modifier for bullshit.
It cycles. The end result is if you did a whole bunch of effort to monetize the part, and made pretty much what you would have got to sell it outright.
Car manufacturers would be screwed. Nothing says you can't take a component out of your car and replace it with after market. People would just sell them to exporters who send them to China to be "refurbished" into brand spanking new, superior, Chinese after market parts. I seem to remember there being a BUNCH of controversy over auto manufacturers voiding warranties and prohibiting customers from full ownership, so that has really good precedent.
If you never actually compromise the IP cop software on device itself, but choose to remove it, no violations of DMCA were performed. That allows that "black" market. Only way around that is to link everyone one of those devices together somehow and argue that the removal of any single part compromises the IP security of all parts. Beyond freaking ridiculous of course, but it's not like old men and old business models play fair.
Enforced how too? The OnStar is not optional? I have to be tracked? I'm warned and then sued if my car doesn't check in?
Which guy would EVER purchase a car like that? Not many.
It stands to reason that many people would opt not to purchase the feature, but still have the hardware in the car. Who pays for that? The consumer does, and probably at a discount price with service contract.
Either:
A) They need to find enough suckers to NOT figure out that the TCO has to factor in monthly service charges. So that heated seat will cost the base part price of $238.83, plus the service charge fee, credit processing fee, applicable taxes, monthly feature costs, discounts, arbitration support fee, lube fee (even though they don't use it and sell it again), general stupidity fee and end up being a $2,345.32 heated seat. This *must* seem reasonable to them.
B) Magically survive when their not-paid-for parts are being stripped and re-purposed as scrap.
Some people's kids man...
