{Khun Mokan, I guess you watch sport in US too much........} Not "too much", zpeed, but "all the time". What you said about sport program on TV in US is true, they all use professional commentator who have been inside the sport for so long that why they all have all the technical information. I understand about entertainment aspect of the TV program but if you look at the way the sport program are made in US, you will see that they can make the program that contain both entertainment and techincal aspect of the game and done it in a very good fashion.
I know there are a few people in Thailand who know what and what not about motorsport in Thailand (the number of such people are the same with the number of your fingers on your right hand, no more, no less), but it doesn't mean the information is not available. What I want to say is the person who make the racing program on TV should....no..not should...must spend their time looking for and learning about those information before make a fool of themselve on TV. They don't have to "KNOW IT ALL" but at least they sould "KNOW ENOUGH" to make a good qualities program otherwise DON'T DO IT!!!!
