I don't understand how can people be so ignorant and think only about their own pocket. Such a waste of resources are hard to stomach.
The other thing that I don't understand, where are those representing the law. Drivers using sidewalks and bike roads can be fined. That's serving as a good lesson, not to mention a very good income to the local budget.
Looks like Thailand needs another 50 years to do things right. No offense.
