A 250 baht helmet from Tesco doesn't do much- it's slightly better than nothing, but that's about it. There would have to be not only an enforced helmet law with substantial penalties, but also a safety standard (DOT, Snell, ECE, whatever) that would greatly increase the cost of a helmet to riders- many of whom would have trouble affording it- to make a real difference in road fatalities.
It's not just a legal or religious issue- it's a financial issue as well.
