1. I am of the general opinion that American highways would be FAR less congested if people followed the passing lane rule. Sadly, they don't. For that matter, busy staircases/escalators would also be less congested if people followed this very simple rule.
2. Choose your speed and stick to it. It befuddles me the drivers who are happily going along at whatever speed they chose, say 60mph. Nobody is in front of them, but for some odd reason, when another driver tries to pass, they suddenly feel a need to speed up to 80mph.
If all else fails, see George Carlin's take on traffic. He used colorful language I can't write here.
Alas though, we should not highjack the thread to discuss highway traffic, so I will simply say the above also applies to WDW's walking pathways. It befuddles me, how many people seem to be offended by the idea of being passed.
