I'm still waiting for my Roadster. I gather The GSM can be set to ON, OFF, or On for 6 hours. And that the GSM allows Tesla to remotely collect information about the car, and perhaps about your driving. I'm wondering if people leave it always off for privacy, always on to help Tesla improve the car or future models by having access to real-world information, or just turn it on when there's a problem they want Tesla to be able to diagnose remotely? Thoughts and reasoning on the topic welcome.
