alt Hacker NewsSpeed limit cameras are highly effective at slowing cars down. They were recently removed in Ontario, and the average road speed increased substantially. The pedestrian death counts spiked in both Toronto and Ottawa this year. This is likely not a coincidence.
But did Toronto and Ottawa have to develop a lottery system to enforce the new systems due to capacity issues? Over the course of a month, it was over 400k infractions captured... 40MPH road.
The only reason for the speed to trend downwards is the increasing threat of a ticket from an automated system that cannot be reasoned with. A real cop generally isn't going to ticket me for going 5, maybe even 10 over a posted 40MPH zone unless they fished me for something else during the the stop. Flow of traffic is everything.
