Your friend, or the new used car owner, will get to push a button every time the car starts, agreeing to the contract. Yeah, yeah, unenforcable, blah, blah. You want to go to the mall, or not?
If we have EU cookie banners every time we turn the key in the ignition, I give up. I'm going to find some 80s pickups in Arizona or something and start stockpiling them.
Yup, there's a "decline" button. The ironic thing is that my acceptance or declination doesn't go anywhere. The original Leafs used frequencies (GPRS) that AT&T quit supporting. Since the now-worthless radio is a useless threat surface, I had Nissan remove it for free. Because CarWings is a mere half-assed shell of what it could be, I declined to spend the $200 on an updated cell radio. So if I do press a button, it's for naught.
Anyway, all the screen says, in essence, is that Nissan is using the aggregate data blah, blah, and if you want to use the nifty history telemetry, well, you're going to have to let the car send those data. Or not; car works just fine if you press "decline".
Sure you did, a contract of sale. That makes you the owner of the device. Should another person be able to access all your computers sensor data just because you let the person use your computer?
Of course my friend can use the sensor data of my car if I let him/her. The question is whether the car company can claim that the sensor data that my friend collects while driving is theirs without informing him/her of it.
