And how exactly is this relevant?? Lets see, drive around in a gas hog of a hot road or jump in the modern EFI car that always runs the same and gets good mileage.....hmmmm.....that is a no brainer. Let me guess, if you had both at your option, a turbo slant six hot rod and an economical modern vehicle you would dd the /? If you say you would I am guessing you have brown eyes......from being full of sh*t........
