If you guys aren't watching F1 this year, you need to be. There have been 5 races so far this season, 5 different winners from 5 different teams. Every race is more exciting than the last. Monaco is next.
I have no concerns for the COTA to be completed on time ... Korea a couple of years ago only paved the racing surface 2 weeks before the race, and the race went off without a hitch.
I used to watch F1 when Senna, Schumacher, Hill, and Mansel competed! Doesn't seem the same anymore!
