Interestingly, they are aimed forward, through the windshield.
The only part of the driver which is recorded is audio.

It seems the "loop" legally must be 30 seconds, which seems
far too little to be of any use.

Or, maybe I'm wrong, but the "triggering" event is 30 seconds
after a crash?

Can someone explain the 30-second rule?
