500 Baht fines didn't work for helmets, so they raised it to 1,000 Baht - still no significant change in helmet use. So I think the figure is too low - let's make it 10,000 Baht and if that doesn't work let's raise ot to 100,000 Baht! Or, keep it at 500, but do active policing (not sitting at checkpoints) and actually enforce the existing law. 🙄
