The only way to action video. Or to slap a wrist, Is to POST a form in! (or see a station and agree to stand up in court) -
If you want the incident to be investigated with a view to the offender being prosecuted, you must lodge a formal complaint at your nearest police station.
Yep did that with the Tunnel incident, attended twice, completed the form (which is actually an accident report form so not best suited to reporting non-accident bad driving/offending), submitted a copy of the video on a USB stick I had to provide (which tells you how poorly they are setup to deal with video evidence)...and heard nothing more... :-(
