Too bad that the cost of tickets are not a good deterrent. Seems like it would be simple to come up with a better by-law by increasing the amount ticketed for each subsequent infraction. Eventually this behavior would no longer be profitable for couriers.
I wonder if city councils have thought about this, and overlook it for economic reasons (increased courier costs would trickle down to consumers), or if we just need better cycling advocacy about these laws (however, I know there are tons of passionate advocates in big cities, so what gives!)? I mean, who would vote against a sliding-scale ticketing law where you get off with a slap on the wrist the first time, but are seriously fined if you're a repeat offender?
