There is a highway in Texas used to speed test cars...

In the early 80's I got a 5 lap hot lap ride in a Shelby Cobra... 180mph on the straight, 120 in the corners at the Ford Proving ground track in Dearborn during a Shelby American auto meet. Got a pin and patch saying how fast we hit... these were NOT stock, they were the competition model and modded more beyond that. Cost me $100 and was well worth it! Doing that on a high speed oval is different than 160mph in the 1/4 mile...
