I reply because "studies have show that claims of studies have show are often false".

There is absolutely zero chance any respectable study would support that focusing on maintaining exactly 110 km in a 110km is safer than allowing a 10% buffer (going 10km over) so you can focus on the road and spend more of your attention on spatial awareness than staring at the odometer.

Second, it is not about "who cares", it is about road design, a road that is up to standards of allowing a b-double doing 110km means a smaller car can safety do 140km or more. It is exactly one way or the other. It is either unsafe for B-Double to do 110km or a small modern car to do 140km. It is simple laws of physics.

You can't see my original comment, so opt to make some nonsense assumptions to feel good about yourself. By God,this place is a cesspit of arrogance.

Nobody claimed any study found that zero percent speed tolerance is beneficial. They said speed limits in general. You're arguing against something nobody ever said.

And no, it's not strictly "if a truck can safely do X then a car can do X+Y. It's not just about physics. There are more cars than trucks, so speed limits matter more for cars. A truck getting into a crash is worse, but less likely. Trucks also already have lower limits in many places, so this isn't even relevant in most places.

You can accomplish that equally easily by sticking to 100 km/h.

What is it with the word "limit" that is so hard to understand? It's not the suggested speed, nor the target speed, nor the minimum speed. It's the maximum speed.

If you stick to 100, then every tom, dick, and harry will overtake you creating a lot of opportunity for mistakes.
