Tell them you are American and you thought it meant MPH 
Okay, so I accept that it's my fault for not reacting to the signage quickly enough, but frak it these things are just blatant money makers for the city. I was driving down the street which is mostly an 80 kph limit, except for one short section that turns to 60 before the road ends that I forgot about (because hell, there's nothing there except the end of the road). What really ticks me off is that I was under limit for most of it going 76, and hell my foot was even off the gas and I was just coasting in towards the end. But of course, there's an unmarked cruiser parked right at the 60 sign and it flags me down. I thought there was something wrong with my car at first.
Bah, just so utterly pointless, and the location has really nothing to do with safety. It's just a money grab. I'm sure other cities are much the same; though mine has actually had people trying to band together and file suit because of how blatant it has become. There was a report released a couple years ago about how their red light cameras weren't making as much money as they'd hoped, so then they upped the number of speed traps to make up the difference.
Bah. Time to sell off one of the cans I guess...
edit: $254 for 16 km over (roughly 10 mph over)
