I've been doing this for months through the chffr app. Get a good phone mount and download from one of these links:
Google app: https://play.google.com/store/apps/details?id=ai.comma.chffr
Apple app: https://itunes.apple.com/us/app/dash-train-self-driving-cars/id1146683979?ls=1&mt=8
The comma.ai app chffr might interest you, especially if your car is new enough to support a Panda dongle then you could record video and help their crowdsourcing effort to make self-driving cars. What I don't know is if their app mandates running in the foreground (which would be kind of silly), or if it does only run in the foreground whether there's already a feature request to fix that.

We Web 3.0 now, boys!
Download chffr here. It's pretty neat, functions as a dashcam and sends the video to help train self driving cars.
It's not a lot to get started. The only thing you'll really need is a mount that holds your phone steady and allows the camera to point out the windshield.
If you really want to help, I'd recommend getting one of these and a panda. You can link the panda to chffr and pass along all that data you want.

They are still accepting dashcam footages
