And in real life we also feel how much we've turned our bodies. And we can tell where the sun is to judge from that. And a steady wind helps in the same way (see, another reason you oughta pay attention to wind direction when you're flying RC!). And I've always been able to tell where the pits are from the constant LAUGHTER, so always know my orientation to the pits. Or when the laughter dies out and I hear scrambling noises, I know I'm flying over the pits. Heck, there are lots of things in real life we use that aren't available in sims.
