Part of the issue is that on a lot of the 400 series highways around toronto there is a speed limit and then there is the speed that most travel. traveling at the speed limit would probably attract a tow truck as I am sure they would assume your car is broken.
9dreizig may have been going 40% over but traffic noramally flows in the 120 - 130Km/h range. I was nabbed on the 400 at 130km/h late at night with light traffic. During the day during rush hour the average speed is somewhere in the 130km/h to 140km/h range with some well over 150km/h.
The rules arent fair and getting caught sucks but the rules are plain to see as are the concequences.
