But, before everyone starts making tin foil hats, you already have a similar system in your daily driver if it was made from the early 90's on.......It's called an ECM, or electronic control module, the main computer in cars/trucks that controls any and all electrical functions of a vehicle.......
they vary by type and brand, have a 15 to 30 second "loop"......if you bring your car/truck into a dealer for repairs, the first thing they do it plug into this and look for "faults" in the system to diagnose your problem. Anyone with the correct equipment can do this...
some of the things found in the ECM is ALL engine functions, rpms,transmission gear selection,brake pressure on the pedal and so forth and so on....by knowing the trans. gear selection and engine rpms, they can calculate the speed of the auto........this and other functions found can tell what has happeend in the last 15 to 30 seconds the engine was running.....
good/bad/ugly, it's already there, and at least on GM products been there since the early 90's........
don't ask how I know this, just take my word for it.....
