Lol, that's kinda funny but could be dangerous for the unaware rider.
What camera were those taken with? You were either on nice smooth roads or the camera has pretty good image stabilization.
The "dangerous" thought was the one I had as well which is the main reason I did the recording.
The camera was a GoPro12. The road was ok.
Oh and tha camera has a remote control that allows me to start and stop recording from the handlebars.
We also have a front and rear facing full time camera system on the bike as well for "other" events.
