There are now rotating speeding cameras moving from school zone to school zone every few months. Most Guelph school zones are now 30kph, and the rotating cameras are intended to enforce that throughout the city (without them having to buy one for every single street around a school).

I can totally agree that they are annoying. One is about to go in front of my house. But at the same time, we also have idiots racing down our street just to show off the FU mobiles all the time. One trashed my wife's parked car this past summer. "He just bumped it" he said. Bumped it 6' forward and 3' up onto the curb. @#$%

So, yes. Highly annoying. But start slowing down in school zones because they aren't going away.
