Police members are human beings just like the rest of us. Plenty people fall foul of the crap infrastructure we have, I don't think much will change unless we redo the way bicycles are catered for on (or off) roads.
Anonymity is a shield from the tyranny of the majority. . . .
I witnessed a novel form of a dooring today. I was walking up St Kilda Road in my lunch hour when I noticed a commotion about 30 metres ahead. It seemed that some guy had hailed a cab. The Cab driver just stopped dead in the left hand lane just next to the bike lane. The guy just ran out and opened the door, oblivious to the bike who ran into it. I could hear the swearing and cursing from 30 metres away but by the time I got close they seemed to have sorted out there differences and were moving on. So I assume there was no damage to the bike or rider.
