Seems to me that a cell phone is much cheaper than the onstar service. No, you can't easily unlock your car doors with your cell phone, and your cell phone can't tell you your gas cap is loose (unless you're too close to it when you get a cell phone call ).

Sure, cell phones are unusable in some places, but I don't want to give control of my vehicle to someone else and then pay them to do so! A lot cheaper and safer to carry an extra key in your shoelace or something.

As for their privacy policy, who follows those? Just like Microsoft follows all their court ordered judgements, right? Besides, even if they follow their privacy policy, they STILL have the info in a database somewhere, waiting to be hacked or accessed by gov't supeana (sp?).
