So only about 30 years of constant pedaling.

It’s not just electric, and it’s not just subcompacts. It’s pretty much every car with a cellular capability (onstar and competitors), whether you have service enabled or not.

Nissan even has in their privacy policy that they can collect your “sexual activity, health diagnosis data, and genetic information” and will sell to advertisers “Inferences drawn from any Personal Data collected to create a profile about a consumer reflecting the consumer’s preferences, characteristics, psychological trends, predispositions, behavior, attitudes, intelligence, abilities, and aptitudes”. Not so realistic until you sync your phone and text message history to the car.

Cadillac here. I just unscrew the cellular antenna from the onstar module before leaving the lot. Looks like the onstar module is less conveniently located for bolts (it’s under my rear seats, I think it’s behind your screen), but that’s a good way to avoid collateral damage to other things on the same fuse. Since it’s a separate antenna from the gps, I even still get navigation, just without map updates. It’s all the good of a cell jammer, with none of the prison or fines. For now.
