^^john - I guess I'm lucky
My height (about 6') comes from an abnormally long "neckular" region
My lower half fits in a miata (older generation - not sure about the new mx5), but my upper half pysically doesn't fit. With a soft top, my head pokes into the canvas
Interestingly, I do fit in a Porsche 944 - in the front seats... Yes, they have two back seats. When I sit upright in one of the back seats, my head sticks half way out of the sunroof (very amusing)
But that said, I've fit in about every other car (including an old old Lotus Europa)
And even with that said - 50%tile (American weight and dimensions) crash test dummies fit the cars for IIHS an NHTSA testing
So the majority of Americans can't claim they don't fit
