I am thinking something like a CVR but video which is always on during the flight and capture the whole flight or the last 30 minutes of pilot action and the outside could be very helpful for accident investigation. No need to publish or even save it if nothing went wrong.

Most pilots won't give up .igc files when they are in an accident; much more factual information available there than with a camera (in my opinion). It is usually possible to sort out what went wrong. Without such data, you are just another person with an opinion.

I worry about cameras not sufficiently restrained during an accident injuring the pilot or passenger...
