105 maximum on the foot. Cruise is 2-3 mph slower. So for the extra agrevation and effort for the 2 mph I just use the cruise at 102(or so).
Now...why should I back off on my speed, when I'm already 60 feet ahead of the guy beside me? And, I've also had my turn indicator on for over 1km: waiting for the empty B-train flatbed beside me to move ahead of me.
It gets back to the point, that at times, speed above and beyond the posted limit is necessary, case in point....heavy traffic ramp merge.. speed up move over to allow traffic to enter the highway safely. But If I"m stuck at set speed, I'm pooched in the right lane, and pray that the clowns and soccer mom's in their SUV's and Lexus' either are not on the phone, or bother to look over their shoulder to check the blind spot. And then once they get out into traffic.....do something that resembles the speed limit.
Just what was this law supposed to address?
Speeding?
Until recently, Ohio had a 55 mph speed limit. And you did 55. 57 would get you a ticket. period. I still feel like a felon doing 62 mph in that state.
Fuel Economy?
Depends on the truck. 500 horse Cat with a 18 double over 3.55 rears on 24.5 rubber...... you can't get her into high gear until you hit 60mph.
Greenhouse gases?
EPA regs for on highway diesels (the R&D cost to manufacturers has basically made Caterpillar say "we don't want to play anymore" and stopped production in the highwy market) have engines produced past 2007 actually cleaning the air.
University of Arkansas studies on the effect of split speed limits (A for cars; B for trucks)show that such policies dramatically reduce the safety on highways. This law, in effect, imposes a split speed everywhere an Ontario truck travels. Even in Ontario. 100 km limit? Yeah, right.
I don't need to break the sound barrier...but the ability to travel at the speed limit in the jurisdictions I do travel in (~90% of which is NOT ontario) would be nice.
And as an afterthought...I have 27 + years experience, logged over 4 round trips to the moon, no accidents.
