As a little teaser, here's an in car video from last season - the colours are a little "off" (from what I remember, brake lights shouldn't be blue) but it doesn't take much away from the experience. Note that they use a "short cut" and the end of the lap, and bypass the GP track, as there was construction work going at the time.
