I bought my car 8 years ago, and I never signed on any data sharing.
When I wanted to update the satnav and enable some additional features (like there was supposed to be internet connection with wifi for passangers), then they hit me with eula. And it was very bad.
Needless to say, I never signed it, but I expect them to take everything anyway.
The shit that will hit the fan will be so large, that many people might not survive it.
The AI bubble is bad enough on its own, but these ripple effects are making it global and cataclysmic.
