Most cars you can't see the nose of anyway. My MR2 road car I can't actually see the front and in the Caterham type thing that me and my dad use it's even worse, especially as the harness holds you to yourseat. It's all about knowing where the edge of the car is and most drivers have been doing it for so long that it's second nature. Surprised by the 'arse lower than feet' thing though, I thought they sat with legs outstretched in front of them rather than up.
