I am now at 515 miles and still have not tried it out. I'm waiting for an safe opportunity. Maybe on a 3 lane going into 2. You know when it is 3 on one side and then merges into 2 once you cross over the intersection. That is always a pinch point that a little extra acceleration could come in handy on. We'll see, I'll let you all know if and when I had to get on it for some reason.
