No, I've never driven out there. But I have driven in L.A., so I know what really bad traffic is like. You're right, Utah shouldn't be complaining about bad traffic YET.
I think most of the complaints here though have related to the horrible drivers. In my experience, they're worse than anywhere else in the US (in my limited experience of driving in L.A., Chicago, Denver, S.L.C.).
I don't want to argue with you- because I like you and I know what you are saying but I've driven in Denver, New York City, Paris and across the country many times, etc. And it seems that no matter where I live that the locals always say they are the worst place for driving. In Denver- I heard that constantly! Those Denverites really complained a lot about road rage. In D.C. I heard that people could not drive worth a darn and all the locals complained about the condition of the roads. In Paris, I was warned about the crazy drivers. The people I stayed with got into 2 car accidents in the 1 month that I was there. Don't get me started about New York City! All I'm saying is I don't know who takes the cake for being the WORST. Because frankly, everywhere has bad drivers. I really am not trying to be difficult though! LOL! Anyways, just yesturday I was sitting at a light- the green arrow came and the people in front of me just sat talking to each other- I waited for a second- then I tapped the horn a little- not a lot- not like I layed on the horn- it was a -honk- that's it. And guess what- the lady gave me the finger. So yeah- people are JERKS and Utah JERKS are especially annoying!
