Had a little private sesh with a friend and played with the Oculus.
Just such an awesome feeling wearing this!

it is interessting to see the headtracking being useful, like at 1min40 where you continue to look at the outside of turn (while the car has already rotated) and then look "over the shoulder" at the other car.

I've been using an Oculus for a little over 6 months now, and I have to say, once you get used to it (maybe 5 minutes or less) it's incredibly hard to go back to a standard monitor.
All that stuff you say to new drivers about using their mirrors and look buttons is natural and automatic in the Rift. I can't say it's made me a faster driver, but I'm certainly more aware of where I am on the track in relation to other cars and bits of scenery - walls especially
