My understanding is that Rivian’s lane keeping (and other features like it) are only possible because of driving data collected to train their models.

It’s not such a stretch to believe that there’s some aspect of this that is specific to a driver or to a vehicle, and so requires that they collect your data. Even if this is not accurate, I can see a business making the decision that, given they need more and more data to improve the model, they would not allow customers to opt-out of that training cohort and still use the feature. Incentives etc.

Directionally though, I am with you on auto telematics data collection; I am not sure you can even buy a new car in the US that doesn’t ship with tracking, and many manufacturers (like the one who makes my car) don’t allow opt out at all. Fcking Stellantis
