Not only drunk driving, but drunk driving to death (especially on the bike) is actually quite a cultural thing here. At least, that is the conclusion I came to after witnessing dozens of those kind of deaths. Rare , very rare will you listen from a Thai person a speech condemning those stupid idiots (most of them quite young) for not taking care about their safety on the road. Sounds weird? Yes, for me and you. Possibly, the Thais treat the death itself differently than you and me, both, let me guess, hopeless atheists. But for millions of Thais it is probably one of the many ways to get a new identity and to be reborn again. Who knows? Not me. And I think not you too.
