Looks like the software is Live for Speed, and that's a commercially available motion platform, though I forget what it's called off-hand. The software is about $40 USD, and the motion platform in the general neighborhood of $30,000 USD.

I would very much like to have one.

Comment hidden because you are ignoring dag.(show it anyway)

Sweet. Love how it simulates acceleration gees by tilting back.

Jeeez that's a tiny room to have that thing in.....

Meh, I think I'll wait for the eventual holodeck/cranial implant.

Uh, why is it going up and down? There are no hills.

It's going up and down because it's not an F1 simulator.
It's MotoGP, and the backward tilting is from wheelies, and the dipping is from corner braking forces.

Look at the turns, when he turns right, the simulator tilts him to the left, but the horizon on screen stays horizontal. So what you experience is being thrown out to the side around a bend, but the world still looks horizontal from your chair. This is what you'd expect from a formula 1 car isnt' it? If it was a bike, you'd expect the horizon on screen to tilt and the chair to angle you into the turn, not away from it. Forward acceleration throws you back, hence the chair falls back, no wheelies involved. Similarly braking throws you forward so you're hanging from your safety harness.

ryan is correct, it tilts back so gravity will pull you into the back of your seat, simulating heavy acceleration.

Ideally the person's center of gravity would remain stationary, but you can see at some points where he's raised and lowered. That's to prep the machine for maximum effect when heavy braking/acceleration can be anticipated (ie the car is going at a really high or low speed).

It was all fun and games until he tried playing GTA IV, and was promptly yanked out of the chair by a stranger.
