I wanted following in camera:
- 1080p @60fps for track videos
- 160+ degree FOV for traffic coverage
- large recording capacity
- auto-on recording feature
- "open" firmware for feature updates
I got one of these:

With 128gb microSD card, I get about 10.5hrs of video for entire week's worth of commutes and any other rides in between. Then I just download over weekend. Or just let it loop recording if there's nothing worth saving.
Here's sample commute, run across 5 cops before I even get on Bay Bridge! Not sure what guy on MTB was doing.
I also use it mounted on bike for track/race videos. I updated it with firmware that has auto-record mode. When bike powers on, it starts recording (have it plugged in USB charger). I have enough to deal with on track days that I don't want to worry about charging batteries or hitting record button at right time.
What are your requirements for camera?
