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).
