I don’t know about your area, but around here, assuming there are 3 lanes, the center lane is the slow one, the right lane is a passing lane, and the left lane is for the 100+ crowd (and I’m not referring to their age).
That’s pretty funny. One of the reasons I love three lanes is that the far right lane is my secret weapon. It is common for people to bunch up to the left, leaving the right lane wide open. When you drive a certain stretch daily, you know exactly where it tends to occur.
