In terms of cameras and close passes, I wish the cameras could be calibrated to judge the speed of passing vehicles and the distance from the camera lens to the passing vehicle, to then automatically cut a reliable section of the recording of a close pass and send it to police (with the rider having filled in a form with their details when setting up the camera, that will be attached to the clip submission).
The idea being it saves riders spending a load of time reviewing recordings, grabbing clips of potential close passes, which they then ask the police to review and judge whether to take action. A calibrated system would only submit clips that the calibrated camera says were too close at the given speed of the vehicle, less police reviewing time needed, freeing them up to do more police action during shifts.
It's not exactly like it's difficult to do either...
This one I got a result from, despite Wiltshire ostensibly not taking operation snap submissions... the van driver behind, however, gave me a witness!
How to achieve calibration? 3 metres of tape measure and your camera, then fade the two images.
It might not be totally precise, but for the far too close, it's striking.
