Ooops, I mean...
Limit is 100kph here, 62mph, left to my own devices in light traffic, I'll just bumble along at about 55-58mph 95kph, there's a "sweet spot" there.
Then if I'm drafting trucks, I'm usually finding I'm going at 105-110kph
In heavy traffic nearer the big TO, it gets a bit nutsy, because they keep branching the right lanes off to nether regions of the metropolises diseased underbelly, and everyone else is doing 120ish, so I find I have to step it up to 110-115kph to have a right to stay in the middle lane and not get shunted off, or shunted into by merging traffic. You just don't save gas by going 55mph/95kph-ish in this kind of traffic, coz you continually have to hammer it to move over and merge into 120kph lanes safely. So you just have to try to go as slow as doesn't piss ppl off too much in the middle lane to keep a steady speed.
I remember The RoadWarrior..To understand who he was, you have to go back to another time..the world was powered by the black fuel & the desert sprouted great cities..Gone now, swept away..two mighty warrior tribes went to war & touched off a blaze which engulfed them all. Without fuel, they were nothing..thundering machines sputtered & stopped..Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice
