Sort of related. BMW has been doing something similar for some time. I bought a certified 2012 3 series back in 2013. New, the car had an optional package for something called Comfort and Convenience Package or something similar to that. It was mostly lighting - footwell ligting, door handles lights, some other stuff. That package was not purchased on the car I bought but all the actual lights were there and someone created a way to turn those things on using a bluetooth/OBDII connector and a laptop. I think the program was called BMW What App?? Not certain of that. Anyway, I added all the lighting stuff...

I hope people don't buy these subscriptions and auto manufacturers give up on them.

edit: words...
