Thx to all for the responses, and for adding personal / upcoming issues ...
I'm leaving CM on the 29th in the AM by car rental to BKK city, aiming to arrive at Airbnb or friends before curfew to safe the hassle of that. Will do a test early morning on 30th in BKK, that I can pick in the evening, so I can make my flight departing at midnight, with enough time left on the PCR certificate.
Seems to be the most favourable for my situation, and definitely price wise when considering all the add ons with flights and extra days in BKK since flights aren't daily.
Also least amount of contact with people, with regards to boarding a boarding a plane and going through 2 extra airports, before I'm on the Int. outbound flight. This, to be fair, is the main reason for driving myself ... putting my faith in the hands of taxi / minivan / tourbus is no option ... I'd rather cancel everything and wait it out, before doing that. Just my opinion of course.
Good luck to all, stay safe, stay connected!
