Schneed: If you come to Virginia, I suggest you don't practice this type of driving seeing as how it is illegal. Below is a link to a site that gives a synopsis of all states then a link to their actual driving laws.
State "keep right" laws
Someone mentioned red light cameras earlier. I haven't read anything about them helping much at all. In fact, you can only be ticketed (at least in VA) if there's a sign saying that the intersection has cameras. And here's one of many studies showing that they actually cause more accidents than they prevent. I must say, one of my two accidents happened because I didn't run a red light. They actually got out of the car and said "Why didn't you just run it? Look what you did!" The light was fully red by then.
I'm looking for the insurance survey now. It was sent to our house a few years ago by our insurance company. I need to try to find it, and will look more. But Im already late for a family thing. Hope the left lane is clear!
