Not quite true as I stated it. You can drive around all you want with that screen showing without ever pressing any buttons. Source: our '11 Leaf.

(Though I'll admit that that annoying screen was at least a partial inspiration for my original comment.)

Can you press decline? I can't read what the other button says.

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".
