You probably see cars with open gas caps driving on the road. well this one is on track. and the video shows you what happens to the gas in the tank if you apply sideways G-force to a car
The story: The car in front of me spilled gas as he was exiting a turn at the track. I forgot to put this up. happened a couple weeks ago at trackdaze event.
Its easier to see at high definition. (about 30 seconds into the video)
