Thai here, there always exception for everything, but some is indeed a standard.
1.I suspect you don't live in Bangkok. Go to BTS around 7-9 am and you'll see. though slow is kinda Thai's trait. 30 minutes late amongst friends is to be expected. We are chill people, a bit too much perhaps. Its always an argument about this topic,for being too nice or too chill brings disorder, compromised laws and we pretty much don't stand up for our own goods.
2.I think drivers license is too easy, and they don't teach you ethics.They don't teach you how serious driving are. 2 lecture, exams, BOOM LICENSE IN 2 DAYS.
3.Hypocrite is also an argument.
4.Our adult culture is not a straight professional looks like in western,
so adult here can express to anything they like without feeling childish
