Here's an in-car video shot with a first-gen GoPro Hero HD video camera mounted on the inside of the windshield of my 1995 track/street Miata (which has a lightly modified 1997 engine) during an NASA-AZ HPDE-4 track session at the Inde MotorSports Ranch track near Wilcox, AZ. I am clearly on the track in this event with some pretty fast cars. I literally had the slowest car on the track on the straightaways in this session, but I was able to be fairly competitive in the twisty parts of the track (this is the fast Config-6 at this great track).
