Hey, if you're looking for a place to relocate that has nice drivers, consider Denver. I'm always pleasantly surprised when we travel south into Colorado and get into big traffic snarls in Denver. Nearly any time you want to change lanes just turn your signal on and someone behind you in the lane you're trying to get into will slow up and leave a gap so you can make the change you're signalling with no hassle. Most other areas I've traveled to it seems like the traffic just gets tighter when someone sees that you're trying to make a change.
In Wyoming we don't have major traffic snarls so the politeness of the drivers isn't tested so much. We haven't been that Californicated yet.
