Enforcing a fifteen MPH difference in speed, between heavy trucks and all other traffic, is going to significantly increase fatalities on that stretch of interstate. It's known as "friction," in DOT parlance, and friction is bad.
Didn't know what it was called but I thought the same thing.
Well, the auto speed limit drops to 65 as well, but it's not as though many motorists will pay attention or anything like that.
I've heard it called "platoon friction", assuming it's the same thing. You're right, this is crazy.
Speed differential kills. Watermelons don't care, it's about control, not safety.
Exactly. Slow trucks require much changing of lanes, and impatient fast lane drivers. It equals more accidents.
