Yeah, Denver drivers are pretty bad.
I mean, in most places drivers are dumb or stupid, not both. I've seen drivers perform stupid actions not out of stupidity, but out of spite. It sucks.
I voted for #1 because I think this is the biggest problem on Denver highways. I've gotten on 1-25 in the slow lane going southbound and passed everyone in every lane to my left. It's dumb. People think because they are in the fast lane that makes them better than everyone else, and they can't stand that anyone might want to move faster than them. They're the center of the freaking universe, after all.
I think most traffic problems on 25/70/225/470/etc would be solved if the "left lane for passing only" rule were enforced. Unfortunately the one time the cops tried it there was such an uproar by the collective prats that they had to stop.
I've weaved before. In anger, even. But when you've got two lanes going the exact same speed (5 under) and a perfect "third lane" going between more than a dozen cars... I'm telling you, it was straight out of a movie car chase - they were lined up that perfectly. I don't regret it at all.
I also want to hear the definition for getting "cut off". I've jumped in front of people before with little room to spare, but I always make sure they don't have to hit their brakes in order not to hit me. They never have to actively avoid me you see, I've already compensated for their driving style.
You see, I always assume that everyone else on the road is a moron and drive as if they're Darwin's mistakes. I've heard that driving as if they're actively trying to kill you works too, but I think that's giving them too much credit.
