I certainly hope there is an increasing trend of cyclists recording and reporting bad drivers.
Since I had my camera, I had reported FedEx once and taxis twice to their respective company
PR feedback.
My helmet cam is a Campark V30 that costed $99US. It was on a sale. Still is. Probably the Akaso would have been better but there was no sale on that one.
My rear view camera is a Kaiser Baas X300. Not so good. Short battery life.
