Both Fastforward and I have built camera mounts for our cars. They mount to the headrest brackets. His isn't shaky at all, but mine does a little. The image stabilization feature helps a lot though. The best mounting position is inside the car where you can see what the driver is doing. That's the whole point. To critique your driving skills. We video tape almost every autocross run we do. There's even one where I lose control of the car and spin out. That was cool! I would like to post them on the internet, but I don't know how.
