Shorter Tracks?
Back when the engineers, etc. were saying,"it's impossible to run under 7 seconds in the 1/4" and they asked Don Garlits... he said ( the best I remember) the only unbreakable rule is "You can't get there before you leave".
My point is technology will keep improving until some day you can run 400mph in the 1/8. Of course the rules will be very different by then. So, is there an answer? How the Hell Would I know?
