Mazda at least has an opt-out.

Why was Mazda not included? Too small? They would seem to "win" in the sense that they allow an opt-out.

Did you attempt to disable the data collection per the third link? (Mazdas are nice. Luckily both of ours predate the new telematics, but I'd like to think I could eventually get a new one and at least disable it.)
