I usually know where all the police/traffic checkpoints are, but last week I was caught out. You can't turn left across a major avenue unless there's a sign or separate lane for that purpose. Anyway, I got nabbed by a patrol for this heinous crime and fined $363,360 which I get 50% discount on if paid within 30 days. As I was getting back on my bike I told the traffic bloke to catch some real criminals and fucked off, furious.
First time ever, but dozens that I've got away with!
