Wow there's alot of law abiding drivers in this forum. From personal experience, about one person in 50 actually drives at the posted speed limits. I suppose it's the proper public stance, but almost everyone in reality is doing at least 10 over the posted limit. Hell, in Florida, they think I95 is the speed limit!!
That said, now that my Z is broken in, whenever I have the chance to jump on the gas pedal, I take it. Unfortunately we don't have alot of roads here, and way too many people for the roads we do have. So even though it's relatively rural, the roads are pretty crowded. The opportunity doesn't come up often enough
