Glad you are ok and sorry to hear about the accident. I got rear ended once and when I asked the guy that hit me if he had insurance he said he would not have stopped if he hadn't had any. That was in a large city too.
I do not see how people live in the Atlanta area. Last time I was up there and got off of the interstate EVERY road I got on was bumper to bumper - unbelievable!! In addition, I have read lately about people getting shot at from other cars on I75 through the Atl area. I do not travel enough to know if it is like that in other large cities but for now I will stay in my two redlight town - it is easier on my E320 anyway.
