Yeah, I'm not sure about that. BMW wants to integrate heated seats in all models and only activate them through a subscription, if I remember correctly.
While that might streamline production and therefore lead to optimizations, I doubt that those will be passed on to the customer. But you now have more servicable parts, weight etc. pp. in ALL models with a chance that they break...
We've played enough of the capitalism game to know that this is not about the customer and a better price for him.
