Most modern cars, especially ones that fit into more "luxury" brands have an app. That app gives you telemetry and location data for a price. It's rather convenient to be able to pre-condition your car, or figure out where you parked in a massive unlabeled parking lot, etc. This is all consented to, but regardless the data is tracked anyway via some GPS/cell system modern cars have. When you pay for it you get more stuff - anti-theft, better tracking, service tracking, etc.
It's a convenience. I'm not entirely comfortable with it but if you want a better-than-decent car made after 2016 you probably have it on-board and unless you rip the ECM out you're stuck with it. Personally, I'd rather pay BMW, for example, for anti-theft and tracking than pay OnStar or another service that is gonna stick me with a ridiculous contract and stuff my car with even more buttons.
