I think the summary here is that, the head/leg room numbers rarely are indicative of whether the car has been designed/tested for taller people. As you mention

I think the summary here is that, the head/leg room numbers rarely are indicative of whether the car has been designed/tested for taller people. As you mentioned telescoping steering, I have to point out the toyota FJ, which I would have purchased because sitting it in was incredible... OTOH, the steering wheel didn't telescope, and the pedals weren't positioned particularly deeply, so while the seat slid backwards with incredible range, to drive it without leaning forward to hold the steering wheel required having the seat so far forward as to cramp my legs.. Just a couple inches of telescope would have made all the difference.
