The title seems much more interesting than it is. I doubt most people have the ability to perform this type of exploit. It would be more interesting if a group would charge X to unlock it for you.
I hope that becomes more common as these types of features become more prevalent across multiple OEMs. I'd pay a tech-savvy mechanic or a car-savvy hacker quite a bit for features that are already installed but locked behind some arbitrary paywall.
I also just hope regulators put a stop to such behavior first, but I kind of doubt that will happen.
