Prob comes down to the particular police officer you deal with on the day. From what I understand, their hands are tied (to a degree) when taking / handling complaints made by cyclists (or other road users for that matter) against other parties - where there are no independent witnesses etc......and sometimes even if there are witnesses
I had reason to complain to a bayside bus company last year, and I did so in writing and I sent a copy of the complaint to the Sandringham police station.
I made it clear that at no stage was I doing anything other than cycling safely and legally along Bluff Rd, when I was brushed aside by bus number XXX adjacent to stop number XXX at XXXXh on the day in question. I also stressed that as a regular cyclist, I am a big supporter of public transport and I use it regularly. I mentioned that while driving a bus in peak hour traffic might be frustrating for the driver in question, the traffic congestion would be immeasurably improved if lots more people left their car at home and rode bikes.
I never got a response from the Vic Police. I did eventually get a response from the bus company, assuring me that the driver in question would be counselled over the incident. I have no idea if that ever occurred. I'm just glad I didn't climb onto the bus that day and break his jaw.
