That's a little funny. People have height very unevenly distributed either in their legs or torso a lot of the time. But a lot of people don't realize that and project from whichever way they are. I can't stand sitting in the back seat of my Model S at all, unless I were to decapitate myself and store my head in the frunk. There's just no place for my head to BE, because I carry a lot of height in my torso. The Model 3 really fixed that issue, by lowering the seat cushion, and with the glass roof overhead, it has about 3 to 4 inches more headroom than my Model S, so I can actually sit upright in it. I was amazed. But yes, I have heard this complaint from people who have very short torsos and long legs, that they don't like the low seat, because it causes their knees to be too high.
