My favorite camera view is definitely the cockpit view, where I can see the dashboard and my steering wheel, and the driver's hand when he shifts gears. I hate the hood view, and the view in front of the hood, which is basically like a bumper camera. I also like the view behind the car, and I use that if a race is REALLY hard and I can't see well in first-person. But, I prefer the dashboard camera, but if that's not there, I'll always use the view behind the car.
I'm kind of sad that Grid 2 doesn't have a cockpit view, I just bought it yesterday.
