I knew an American lady who had a train on her husbands retirement visa, Unfortunatey he had a heart attack and sied. The wife was give 14 days to leave Thailand at a very emotion timme to pack up, end the lease, sell car, bikke and furniture. I would never recommend a trail on someone elses visa.
I did my 90 day report at Chiang Mai Airport Immigration recently, Drive through window is for cars, bikes and pedestrians. I only needed my passport and it took less than 3 minutes.
