Hi TeichRA,
I think know what you're talking about. I've actually been lucky enough to have driven two FFH's. We test drove the first one that showed up in our area in early April (we already had ours on order in March).
So how to describe it... I noticed in the FFH that I got to test drive that there was a black plastic(?) rounded panel that sits just below and down from the steering column on the inside of the knee panel? It sits basically right above/behind the top of your foot if your foot is on the brake pedal? I noticed that there wasn't a whole lot of wiggle room when switching between the go pedal and the stop pedal, and I bumped into that panel a couple of times, and even gave it a good look when we got out of the car at the end of the test drive. I could swear though, that in our FFH that panel does not protrude anywhere near as much as it did in the one we test drove, as I have not noticed it or bumped it yet in our car, while wearing the same 11.5W shoes mind you.
People may think I'm crazy, but I think there may be some differences in the placement or protrusion of that rounded panel in some FFH's. For what it's worth the FFH we test drove did not have navigation, it was a 501A. The FFH we ordered and now have and love is a 502A with the works.
