It is never going to happen and certainly not in the next two years.
Thais obviously do not have a clue what it takes to build and host an F1 race - even if the road is already there.
The hotel security guards, with their little red flags trying to stop the traffic so that their precious guests can get in and out of the hotel, will need a major re-training in order to become stewards.
Oh - please note Thailand - you have to PAY a lot of money for permission to hold a race.
Money that Thailand does not seem to have at the moment.
