Just fyi - if your car has been manufactured in the last 10 years by a modern corporation(ie - not a Lada) it will have a black box already that records everything about the car's systems. They don't record sound from the cabin, but your speed, throttle position, movement of the steering wheel - it's all recorded.
I mean I have them in both of my cars, but in some places like Austria it's straight up illegal to have them in your car. And in some others like Germany you can have it but the footage is inadmissable in court because the other person never agreed to be recorded. The built in telemetry recording is legal everywhere though.
