I put dash cams in all my family's cars. I have G1Ws mounted in two cars and currently use a GoPro as a dash cam in my Z, but am about to get a dedicated dash cam.
This G1W has been really easy to use and convenient. Also takes great quality video and audio. Its funny looking at recordings and hearing our stupid conversations and me cussing at other drivers. Besides being entertaining I think its a great relatively cheap purchase that could really come in handy.
