Panda, I objected to a speeding ticket 18mths ago for doing 67 in a 60 zone & got off...I went to the exact site that was stated on the ticket, took a photo of the 80km sign that was about 20m away and sent it, along with a letter explaining why I could've been doing that speed (basically, I mentioned that
1. I was either slowing down from the 80, and left it a bit late...
2. I was prematurely speeding up.) In the letter I mentioned that I hadn't had a ticket in over 10 years, I make a point of not speeding in built-up areas (didn't mention open road

) and that I thought it was "very poor form" that they would resort to parking a camera car within a 20m vicinity of an 80km zone...I also stated that I believe that the area that is zoned for 60km should be reviewed as it is not near shopping, school, or residential zones, it has a service lane running parallel, and that it is on a main hwy...
Not sure if they read all of my letter, or infact believed me...but it got me off the hook!
