I've definitely got to spend some time working out how to edit the video once it's captured.
For some things the 360 allowing user interaction is great, but for most of what I'm hoping to use it for a 2D 16:9 video would be more appropriate.
On the cars the 360 wouldn't be too bad as the "home" view would be set much like a regular GoPro, but would allow following of the scenery or other cars/views/angles etc as they interest the viewer, but a simple video with some direction would be the more usual.
I know from watching 360/3D videos myself, I end up turning the cam all over the place, losing interest in whatever the person filming is trying to show and not bothering to watch it much longer of it.
