The automotive OEMs are really bad at monetizing this data. How much they make is not how much could be made if the same data was in the hands of more capable entities.

So you as a privacy-desiring car buyer could offer 2 or 3 times more than 60cents to the car OEM. Or, even 10x more. The monetization of that data by the third party surely cannot be 10x their cost - that would be an enormous margin that seem unrealistic. But increasing the price of the car by $6 is almost a rounding error to the car price.

Plus, if you were allowed to opt-out, the rest of the opt-in data from other people become _slightly_ less useful.

Therefore, all the gov't needs to do is to mandate that car manufacturers offer the option at a reasonable price (where the 10x price is considered reasonable).

I question how much they could really make though. It seems like my phone has better data on me and where I go - it is always with me and I use it for more things. Thus the car makers have data but it is a lower quality source for more things. The car makers also have less direct actions they can take - they can't show a video ad while I'm driving (unlike many phone apps) and when I'm not driving they can't do anything.

They do have better information about maintenance needs of my car. However they are limited to giving that to the dealer who already can guess most of that anyway.
