Those Malaysian dudes like to get their oats in Thailand, they will use the new trains for sure. I can't see them going to far beyond the border towns, not when there's rumpy pumpy to be had 24/7 there.

You could argue that F1 has arrived in Pattaya already, late at night or very early morning when there's little traffic, Some people drive very fast when there's little in front of them
