You're kind of right. I don't believe Thai's fail to check their blind spot because of laziness. It's ignorance.

Not long after my then gf, now wife and I came to Thailand, we went somewhere with her mother. I had a Intl. drivers permit and she asked if I wanted to drive, so fuck it why not. Within a few minutes, she asked my gf "why is he turning his had, can't he see in the mirrors?".

She is a retired school teacher, and she had zero clue about the concept of a blind spot in a car. I can count the number of times I've seen her wear a seat belt, on my fingers (in 8 years).
