Since you being wise in doing your homework way ahead... Just an FYI, there has been talk for years about this, but the new Gvt now in power has made it a priority to incorporate mandatory Insurance requirements in the next board meetings. Having said this, not official yet, but just good to keep an eye on the Thai news and regularly check the Royal Thai Gazette for the official list of changes that have been stamped and approved into law. Hope this helps and best of luck
