I hear you, but the vast majority of Audi customers just won’t care about this DRM or property rights on their car. If they’re leasing then it’s irrelevant as it’s never their car in the first place. It just won’t even be something that they even consider.
What their customers will care about is the fact that they don’t have to financially commit to getting an “optional extra” up front, but instead can pick and choose when they want to use it.
