You have no understanding of Thailands approach to decision making. Usually research is performed on a subject, data is collected, decisions made on the data and an announcement made. However in Thailand the opposite is true. Here a brain fart decision and announcement is made first, followed by public outcry which is researched and finally the decision reversed. This approach is also useful for the government to gauge just how much it can get away with without affecting front row at the trough.
A good example a few years ago was the announcement, just as people were climbing into the back of their pickups for the annual run home to Isaan for Songkran, that it was now illegal to tavel in the back of pick-ups. Obviously, to everybody else, this without notice decision puts a huge spanner in the works for millions of people as all other forms of transport are talken, booked, unavailable etc. Fortunately one good soul lifting his head from the trough for air, somehow heard the outcry, and possibly concerned the turmoil may affect his revenue stream somewhere, reversed the law just in the nick of time and they all lived happily ever after (well, sort of).
