Will the black box record the fact that the driver is distracted with: (a) texting, (b) wolfing down a mcbiscuit, (c) fiddling with GPS, (d) fiddling with the passenger, (e) passenger ... with the driver, (f) putting on makeup, (g) all of the above. Probably not. Box will record only mechanical issues?
A real black box don’t even record those. It only records aircraft parameters, speed, heading, altitude, etc. The voice recorder pieces everything together.
