The average car has well over 100 sensors and the scan rate are in the milliseconds. Datalogging for a mile creates a massive file to analyze. The vast majority of data storage in the modern automobile is for a dozen or so select sensors and then just a few seconds, typically 5 to 10. My little handy-dandy interface and laptop connected to the proper port can tell me mileage, key cycles, and VIN. Depending on the vehicle, I might also get if the rev limiter has been hit, anit-lock brake data and throttle position maps. If you are in an accident and there is near-deployment or deployment data on the airbag module (required by law on 2013 vehicles) I will also get seatbelt, headlight, velocity and acceleration maps. The near deployment is volatile, the deployment is a hard burn.
The "easy" big three for the OPs question is probably McDonalds, Cigarettes and Alcohol, of which only alcohol accounts for deaths of innocents. Knives, blunt objects and ladders are pretty high up on the list. Nothing is even close to "terminated pregnancies" which are abortions, and are still listed in the annual death tallies in the US.
