Well it's not surprising at all
As soon as you step from the pavement onto the road
You are fair game !
Thai drivers / riders don't like to stop or wait !
Head protection on motor bikes normally consists of
Supermarket plastic shopping bags or straw hats
Children are balanced precaresly on the handle bars
Whilst a case of beer or live animals are securely fastened to rider
And rear lights are obviously an expensive option so not included in the bike purchase
