To be more clear, Nashville ranks 12th worst for congested traffic. I don't know if that is just semantics or not.
My automation business has been in downtown Nashville since 1996 and I made the drive every day until 2001, so not that long in the grand scheme but I have to drive to customer sites all over the southeast, so it balances out for the most part. I got to work very early and always missed the morning rush hour traffic. I would usually hit the afternoon rush.
Again, I cannot speak to how it is daily driving in say Oakland or Miami, but I do know if you drive at the stated distance from the car in front of you that the drivers manual states, cars will just merge in front of you, over and over and over. It is quite futile. And yes, when I was a younger man it was frustrating. Now a day's, I just drive and don't think much about it.
Let's use traffic construction as the example. You are driving, you know about construction ahead from the radio news person so you promptly get in the correct lane, you see the multiple lit signs telling you to merge, and you see the merge cones, You also see several cars making every attempt to get one car ahead by ignoring all the warnings. No, absolutely not will I let those rude, knuckleheads in front of me. I am not be mad but principled. Judge me if you want to.
