We never discussed about that subject. Now you changed subject, just because you realized you were wrong on the main subject.
However, if I drive motorbike from Chiang Mai to Phuket? How does that make me an idiot? You can park until you come back, as long as you are able to pay in some way. If you know how long time you will be gone, you can just park your motorbike and pay 70 baht per day for long term parking.
Everything else, just has to do with experience. If your opinion is that you should not do, then just refrain from that. I have been driving cars, lorry´s and riding motorbikes for more than 25 years in Thailand. Not an accident.
