Just buy a ticket and go home. Try entering Thailand again next time.
Although there are rules on how many border run or entry by air, I believe there is also a clause stating "It is at the discretion of immigration officer to approve or deny entry to the particular applicant if he or she believes ..... ".
then drive as fast as you want and get yourself killed in the process. You'll probably get more attention than random farmer's body lying at the side of the road. Farang do get noticed more, dead or alive. Life is indeed cheap in Thailand, even foreigner's life if he/she choose to.
like I said before... You don't like the way it is, then you can leave.. go elsewhere. Or maybe you can file a lawsuit against the authority and see if that helps? 😁
