It'd be a bold move after the lawsuits and data breeches Volkswagen has faced.

Meta has 3 billion daily users across products and brings in $165 billion. Their entire business is your data and they get about $55 a year off of selling yours. (I picked them because they have little revenue other than ads, though even then, not all of their ads have anything to do with your data, but I'm estimating in your favor and calling 100% of their revenue a result of collecting your data, because they're probably the closest to it at very large scale.)
So even if a car company was as good at collecting and monetizing your data as Meta, it couldn't meaningfully dent the price of a car. It couldn't even charge the batteries for a week. Data is cheap and highly scalable, cars are neither.
