Thanks, but I think having nothing there at all would be even weirder..!
The VR experience in sim racing is unbelievable, and impossible to describe adequately to people who haven't experienced it themselves. The sense of presence is quite remarkable with proper head tracking, 3D stereoscopic vision, and surround sound. You feel you are planted IN that car, ON that track, with REAL opponents around you. The whole thing just comes to life. Quite apart from that, the sense of scale was the next thing that hit me. The track and surrounding environment is part of a bigger planet. Park up at the top of Eau Rouge and get out of the car, then look back down the hill and wait for the rest of the field to lap you. It's just like being a spectator at a real racing circuit, and tracks that I thought were pretty flat in 2D reveal all sorts of elevation changes and undulations in VR that you just don't normally notice.
It's incredible, it really is, and a perfectly natural fit for cockpit-based sim racing. I would urge anyone with a capable PC and an interest in sim racing to jump on the Oculus sale right now. You just HAVE to try this, and there's no going back once you do.
