They showed that on the BBC over here a while back, as you say it was a very good promo.
Interesting that the track design has borrowed some bits from other tracks used for F1 from around the world.
The season has started pretty well, with no one team/driver dominating the first two races.
However, I think that the weather has played a fairly big part in that.
Hope the circuit gets completed in time for the race, and all goes well.
