You CAN get a 5 year license with a DTV (after you have held a 2 year obviously) at least you can in chiang mai, so theres no reason to assume you wont get a Thai IDP also.
But you cant go from no license to a 5 year (and IDP) you always have to go through the provisional 2 year process no matter tha visa class theres no bypassing that.
Noa Cohen Well those are the documents I brought.. have a Google but they are the kind of stuff expats get over time, so they see that. Also obviously they react differently with a few million in cash in your hands. That's just how it is, the rules they say prevent sign ups, are all discretionary.
But that said.. Also, Pink ID card, Yellow Book, conservatively dresssed, handled in Thai, and my number was still in thier system from over 15 years ago when I had one with them before. Plus was also depositing real estate land purchase amount of cash.
