this has been going on for several years and new cars from 2008 (IIRC might be 09) on may have it installed already. the data is stored in the AirBag Module Memory. It monitors certain sensors like TPS, MAF, ABS, Steering, VSS, etc. There are already lawsuits going on to determine who owns the info. The dealers say they own the data because they own the program and installed it for their R&D purposes. Procecuters want it so they can use the info against you, insurance companies want it to determine "At Fault" and the vehicle owner should own it because he bought the vehicle. Rental car companies have used the info to determine fault. When i researched this there were only a few companies that had the program to access and read the info.
