I have been visiting Thailand for nearly 40 years , sometimes 2 and 3 times each year.
I always rent cars - even in BKK - and have criss-crossed the country from North to South dozens of times.
I saw many accidents happening, but fortunately never got into one.
I know that people tend to drive like crazy, so all I do is what is called "defensive driving" .
Um other words, always expect the unexpected. Always drive with an eye on the road and an eye on the mirror.
Regarding the article and under the pandemic circumstances, I would say the lady doesn't have a clue about the things she is talking about ...
