Car camera.
 

That seems really expensive... for that money, I could buy a GoPro or something else much more useful...

It shoots 1080p, has wifi, gps, and acceleration sensor.

No 720P @ 60fps and it's odd that they don't seem to mention anything about loop recording.

Pfft, go organic, more realistic feel to the video.
