Well bear just so you know i would never really "FLY BY"in that area you patrol.
A good speed there is about 114.4 km/h You know just so the radar wont round it up 
You know though sometimes if i see an officer parked on the side of the road or happen to noticing him doing some sort of speed enforcement.
I go in the right lane and do exactly 100 km/hr, sometimes they look at you funny as every thing else on wheels is flying by you.
In fact one time i had an officer follow me, he must have thought i "detected" him or something. It was really late at night and the flow of traffic was very fast 125 + and i was the only one on the road going 100, except for maybee a few slow trucks around 110.
It really depends but your area is bad for "speeding."
Lots of cops, mainly all patrolling 401, just 2 lanes, grass / gravel median where you can easily go X ways to do speed enforcement, and way less volume than gta = gives officers alot more time to deal with even the "slower speeders" that normally wouldnt even get a ticket for going 120-125 in the GTA area.
Do they ever enforce the "stop sitting in the passing lane", move to the right except to pass out where you are?
