I don’t want to ban it. Some people apparently want it (well, or at least the price reduction that comes with the auto companies having a new revenue source). I’m hesitant to try to impose my preferences on them.
I just want an option to pay regular price for a car myself and not have everything I do be data-mined. If it costs $N to pay your costs and make your profit, just charge me $N. I just want to be the customer in the relationship, not the product.
They operated just fine like that for decades. I don’t see a need for that to change.
