This morning on a 25 km drive from a village of 400, to a city of 400,000, I passed water buffalo and cows on the road, 90 year old ladies on bicycles, one pedal rickshaw, farm tractors and trucks, suicidal punks up on souped up 115cc motorbikes, families of 5 on one motorbike....7 sleeping dogs in the middle of the road......no snakes.
Any or all of the above are prone to be coming at you from any direction, legal, or not.
You rarely see a traffic cop, but occasionally see checkpoints for various specialised enforcement. (helmet, registration, seat belt, etc)
A friend tells me when they do the rare dui enforcement, they have a rolling lab, complete with ATM to pay the fine.
(Or bribe)
Thailand is kind of at the upper limits of developing country status, but probably wont progress for decades.
This is a country that attempts to battle massive flooding by putting a handful of military small watercraft in the rivers, revving the engines to push the water out to sea.
