I tried it out today on my commute to and from work. It worked great! I didn't know it took audio too; good thing I didn't swear at the car on my bike path.
It picked up a lot of the wind noise though. And the bouncing; yikes.... it is a bumpy area!
After watching the replay when I got home(no view screen), it is something I can improve on. Glad I bought the handlebar mount. If I had it attached to my head, you could get motion sickness from watching how I am always checking my surroundings. Head on a constant swivel.

It was incredibly light traffic today, which has to do with the civil unrest going on. I am going to keep the camera rolling as I go.

Geonz, good call on the recording of people. I will look into the rules here. I don't know where I could find that, but I will look around.
