If this is the same one/linked to the same comments then I've already thrown in my opinion. In the end, I could tolerate the 40km/h limit if it also meant a 120-140km/h limit on the 400 series and 100km/h vs 80km/h on the rural routes up north. That said, I'd rather they keep the city limits as-is at 50km/h, as lowering the limits won't do anything but allow for more ticketing/fines since people will drive the speed the road allows. Honestly, I'm sick of breaking the law when I do 120km/h or so on the 401 when it is wide open, or doing 90-95km/h on HWY 35 trying not to be run over from behind on my bike.
Also call me heartless, but if the real issue is pedestrians walking in front of a car at 50km/h and getting hit, then why are we the drivers being punished for something pedestrians keep doing? If anything, dropping speeds will make MORE pedestrians step in front of cars since the risk is less.
