My cell phone has the ability to record MPEG movies. So I set it up to default for movies, unlimited length. Should something strange happen, say runaway Prius or running out of fuel, I'll try to start the camera and put it where there will be a visual and audio record of how I addressed the problem. I lack Great Expectations that "something bad" will happen but the time to configure the phone for a data recorder ready is before one becomes ... anxious. Bob Wilson
I doubt the first thought in your mind if this ever happened would be to take out your cellphone and start taking a movie.
