Since I have always lived near the I-95 corridor, I have seen quite a few bad drivers in various areas. For a long time, I would peg the New Yorkers (NYC) amongst the worst. I learned later that there certain "rules" you have to learn first and then it "sort of" makes sense.
I wasn't until I was in Boston and in a cab that I quickly revised my opinion. Bostonians are the worst drivers I have ever seen. Talk about just plain bad and nasty too! They don't let you cut in, even if there is 90 degree turn in the road - they don't slow down for nothing, going from 3 to 2 or 2 to 1 lanes is an exercise in playing chicken, and the list goes on.
I'm a long time Washingtonian (who lives elsewhere now) and I have to admit they can be pretty bad. My favorite one is where you are on the beltway and you watch an idiot realize that his exit is coming up fast and they are in the fast lane. They simply floor it and go from the left side all the way to the right side trying to catch the exit and totally oblivious to the other drivers... :jaw:
