the rule as I got it states, no loose objects IN car, so if you have a bulletcamera on your car outside and the recorder on the inside your trunk its quite ok.that's at least what we were told.

in case of accident, and you don't have a helmet on, a loose window mounted camera or other loose objects in car would be very bad.

filming accidents and putting them on net however is not popular though.
