First thing to consider in Thailand is: type of vehicle and usage of it. Cars are "luxury goods" and are taxed accordingly eg. I bought a Subaru XV new in Thailand. Cost around 1.2+m baht and therefore 30% more than the same vehicle in Australia.
Anything with an open bed however (Hilux, Ranger etc) is a different category and is cheaper than Australia by a decent margin, but heavier on fuel of course.
Second hand vehicles of any type are outrageously expensive when compared to home country prices.
You're prolly correct - too complex. Plenty of detail in Thai language, traffic lights named, school on the left where to turn etc etc. Route highlighted and colour used for this. They could actually use it to find their way. Lesson learned!! 😉😉
Actually not hard and fast. I went to Imm in Korat with a really good hand drawn map (I'm a draftsman) and it was laughed at and paraded around the office so all could see how laughable it was! A google map was demanded (in fact it didn't even show where the house was. Ridiculous.
Wrong. Medicinal prescription skin ointments I use are not available in Thailand. "Breathe Right" stickies not available in Thailand (useless knock off's from Lazada). Etc.
