I see the value in a dashcam for the bike, but have not yet found all the features I want.
The one that I like best is the Innovv K1
Front and rear recording. Sharp pictures. Cameras small and easily tucked out of the way. Automatic recording in selectable chunks of time. Shock sensor triggers automatic saving of incidents. Decent results at low light levels. Records up to an hour while parked. GPS to optionally save speed / location.
There are two issues holding me back:
I'd like the option to use it as an "action" camera, and the sample videos I've seen are a little bit jerky. It's fine for a dashcam, and good enough so I can review my lines through some twisties, but not something I'd use to make a movie. I suspect this is caused by the K1 alternately saving front and rear frames. Maybe it could be configured to record front-only?
In the event of a hit & run, I think that the image of a license plate should be readable from more than a few feet. Most dashcams do not record a clear plate image, even at normal following distances in city traffic. Maybe when 4K cameras and fast processors become cheaper?
The technology I want is possible, I'm just waiting for it to be available and affordable, while realizing I am losing the considerable benefits that are available now.
