I understand the desire to make things more logical like the German driving system. I wish we had an autobahn and autobah rules and highly trained drivers too, but this law always struck me as half-baked and frustratingly ambiguous. Near where I live, we have multiple 3-digit interstates. That is, they are sections of interstate that defy the usual convention of odd-numbered north-south routes and east-west even-numbered routes. 3-digit interstate combine highways or circle around cities or take you to tunnels, etc. The result is lots of sections where traffic merges from the left, you have to exit from the left, or the interstate divides into two other interstates and the former left lane is now the right lane. In those very same sections, you have signs reminding you that the left lane is for passing, not cruising. The problem with this is that everyone takes the left lane as a license to go 80+ mph. What if I my left exit is coming up in a mile? Do I "go with the flow of traffic" and risk being the rare car that gets a speed infraction that day, do I wait until the the very last few yards to get in the left and take my exit, do I get on the left and go at a speed I'm more comfortable doing within a mile of my exit(speed limit + only 15). It's all nonsense and feels arbitrarily enforced based on the whims of the state troopers that week.
