In vein of your reply, I'll simply say "Stay out of the left lane." The VAST majority of collisions I've seen which involved a driver exceeding the speed limit were caused by people erratically impeding traffic by cutting them off in the left lane. When I say "I've seen", I mean "I've personally witnessed". It happens constantly in traffic here, and it's usually someone doing 50 in a 70 cutting into the left lane in front of someone doing 80, without bothering to look.

You'd blame the "aggressive" driver doing 80, when it fact this is 99% the fault of the slower driver.

I see slow drivers in the left lane CONSTANTLY, and it irritates me both as someone who drives faster, and someone who understands basic principles of driving and statistics.

If you want to drive slow, fine, go for it, but do it in the right-hand lane.

The amount of traffic collisions and fatalities from speed would be drastically reduced if people in the US just drove like decent people. We have a much higher rate of fatalities than even on the Autobahn, because of people impeding the flow of traffic and generally failing to signal intent before making erratic movements much too slow.
