Now that they've laid the base course of tarmac on the COTA there's a nice video put up on youtube which will give us all an idea of what to expect come raceday:
The only question that I have, and I don't know the answer, is whether this circuit is going to be clockwise or anti-clockwise? Is turn 1 on this video going to be the last turn on the track? The incline, blind crest into 90 degree bend and decline into turn 2 would make for an interesting start
