I have found that I like the fact that the K5 stores and tags files when the G-Sensor signals. I find that the video clips in the accident folder are, well the more sensational of the captured video, and having them automatically organized, saves me time when I go to preview or edit a ride.
Update 6/2/21: I found out the hard way that setting G sensor to max will lead to many short clips in your Accident folder. Word to the wise: find the G setting that works for your bike and riding habits.
