It is EURO5 or EURO6 emmision norm. It also handles firmware updates, reaction to Volkswagen cheating. Car needs to be online, check for latest firmware and all sort of nasty DRM.

There is also a black box, that records position and speed. It may call emergency if it detects crash. If DRM is violated, car may refuse to start, or only drive like 50 kms.

I don't have a source, but anyone should be able to find relevant articles.

That's just creating a blackmarket for people that can crack the DRM without the car losing functionality.
