We may be getting a little too high tech here.

I don't doubt that one bit! I have OnStar in my car and every month I get a diagnostic report via email that tells me if I have any problems with any of the systems (brakes, transmission, cooling, etc) in my car. It tells me how much oil life I have left and how many miles were on the car when the diagnostics were run - sooooooo, there has to be a monitoring system in place to allow OnStar to run those diagnostics from a satelite!!!
