After a weekend of waiting, the rain finally came on Sunday. It had been forecast for Friday, but Friday stayed dry. It was forecast again on Saturday, but Saturday was dry as well. In the run up to the Grand Prix of Thailand, Sunday had looked like offering the best chance of remaining dry. But that forecast proved to be wrong as well.
The trouble started as the Moto2 race was about to get underway. A few raindrops on the grid quickly turned into a downpour. After a brief delay, the organizers started the race, but it would only last 8 laps before conditions forced Race Direction to red flag it, spray and standing water making it impossible to complete the race safely.
Several abortive attempts to restart the race followed, but when another downpour started as the Moto2 bikes got halfway round the track on the sighting lap to the grid, the red flag went out again and the race was called. With less than two-thirds distance completed, half points were awarded, much to the consternation of anti-decimal faction of the MotoGP paddock who abhor the ugliness of a points table which does not consist solely of integers.
