First of all, I don't wish to live in any of those places and most thirty year olds (like OP) don't wish to either. Second, I have traveled the entirety of Thailand from north to Phuket on a motorcycle and it was amazing. Why do you need to make personal attacks against strangers on the internet, do you simply have too much time and nothing to do?
I'm really confused. Where exactly do you need to commute to in Chiang Mai if you are not working there? There are cafes and coworking spaces everywhere. Supermarkets, 7-11s around every corner. Where exactly do you need to commute to, or am I missing something?
pretty small town if you ask me, usually a bicycle is enough for me to go everywhere and much faster than being stuck in traffic. Also this is Thailand, you have 1000 different options for food, coffee etc within a half KM radius. You also have the bicycle sharing stations they added all over Nimman, Old town, and riverside areas
Why would you need to have a car to live in Chiang Mai? When I lived in the US, so much of my expenses went to my car and CM is a small town, a bicycle or motorcycle is more than enough, you save tons of money, and healthier at the same time. Grab is cheap as well.
I've been to Thailand like 30 times and never been asked for one, people just want to get through Suvarnabhumi and Don Muang as quickly as possible, the queues would be absolutely atrocious if they asked everyone to show a flight out of the country
