Moved back to AB 3 years ago. Don't know the stats, but can tell you AB drivers in general drive way too fast.
I've been driving in fog at 50-80 and can only see the next power pole (approx 100m) and people are passing at about 120+.
Drivers here are much the same as in that Q place (in eastern Canada) : NUTS
Do the math: you only gain a few minutes at best ! (and burn a lot of extra fuel)
And if you got tagged in town too fast , you rightly deserved it. Kids/people can walk out from between parked cars & you have very little if any time to react.
A lot of research went into the limits. They are there for good reason.....
