You want the chair? Just go to your state penitentiary and be accused of some crime 10+ years ago. Oh wait, you mean the chair the guy is racing in. My apologies, demon of speed

Radicool, I can recall seeing a video online featuring the Fina McLaren racing around Fuji in the MUCH older days of GT4 news. I recalled seeing a camera view where you can see the machine from the roof of the car. I think it's only going to be in replays, I'm afraid.
If you GT3 gamers have a Super License in the game, you may recall Formula GT. I believe in two of the models, there are two different camera views. The first special camera view (F/090 I believe) was one where you looked over the driver in the F1 car and if you notice carefully, you can note the driver moving his/her hands to try to steer the car. Another F1 car has a similar view, but you look over the driver from the right side. So if you have GT3, just go to Formula GT, go to any race event, then go to "Preview." If you can choose a car and a camera view, take a look at all the different camera views available for some of the F1 cars. Keep in mind that when you select "Preview," you'll get a random replay style. So if you can't have any real control of the action, just cancel out and go to "Preview" again. Keep on doing it until you can finally view a car and cycle through the camera views.
To make a long story short, I wouldn't be surprised to see different camera views for certain vehicles. Certain unique views would be fun.
