Another ill-conceived initiative to benefit the Thai economy by encouraging businesses (like vans) the pulling the rug out from under them.
It not unlike the idiocy bruited about that wants to limit the hours of bars that have just reopened after two long years to conserve electricity.
that said, i live on soi 11, and there are so many vans that you can no longer use the sidewalks near the Ambassador complex. I counted 12 vans the other night.
