> I can't even count how many times I have seen a tractor-trailer in the left lane at 70 mph passing a tractor-trailer in the right lane at 69 mph, as passenger cars stack up behind them. It creates a dangerous situation that I can only avoid by slowing down or exiting the roadway.
Presuming the max speed was 70mph, your post epitomizes the real danger. Traffic should not stack up behind vehicles traveling at the maximum allowed speed. Or at least, it should not stack up in a dangerous way. Twenty vehicles stacked up at proper following distances, all traveling 70mph, is actually optimal. Yet you seem to disparage it. You will never achieve optimal traffic flow if the general attitude toward actual optimal patterns is disdain.
If the max speed limit was above 70mph, ignore the preceding paragraph.
