When a sign at a merge says, Right Turn No Stop, it really means it. You don't want to stop or even slow down. You want to speed up so you can merge with the fast going traffic.
I have almost rear ended many a car fearful of merging. I don't even look behind at the traffic coming at 60 miles per hour because I have to keep my eye on the car in front of me. One swing of my head and it's all over.
I just wonder though, whose fault the accident would be.
