Apparently not this much...
Got this snap yesterday on the way from CNX to BKK (driving).
The guy underneath was not too impressed at my passing by and rubber-necking from across the medium strip, U-turning down the road, slowing to almost a holt to take the picture, U-turning back again and pulling over to take the above picture (the ones where I pulled up on his side of the road were too close up).
Fukn hilarious - though someone will be losing out big time on this. I don't think insurance covers this type of damage, that's assuming the driver had a licence and the car was registered and insured (unlikely).
It's like some fukn he-man quest to see who can jam the most on their trays. I know they take pride in it. I've overheard Thais boasting to each other of how much load they carry.
