I hope I didn't give the impression that drivers in the Seattle area are predictable. they are aggressive and unpredictable, which is why it's not uncommon when a light turns green here that folks don't go because you have to see how many assholes are going to continue on their merry way ignoring their red light.

I hate the over courteous thing as well. I t-boned a vehicle 3 years ago because I was driving in the far lane and the other two lanes were backed up so they courteously waved this dumb lady through and she turned right in front of me. Lady didn't even look. Injured my leg and hip and wrist trying my damnedest to stop, not to mention the whiplash. Still makes me so angry, my daughter and I were injured, our almost brand new car will forever have an accident on it's history. 18 months of pain, doctors visits, PT. All because a couple of idiots thought they'd be courteous. We're better now, but I still have random pain in my rt knee and hip.
