While I wouldn't venture out on the roads here on a bicycle, there are many that do, but then, they live here, know the score and are aware accordingly.
Check out channel 32 or 34 - there are always examples of horrific Thai driving..........
While nobody is premeditatedly murderous, many motorized road users end up being so, mostly due to poor driver training and attitude.
I regularly see groups cycling south along the busy road next to the river with pickups and trucks flying past, and wonder why they think the inhaled pollution and risk to life and limb is worth it.
This is surely quite a common problem, and yet the gutter fitting guys don't offer what would be a very simple and cheap addition for them to install for more profit.
Whenever we needed gutter repairs, contacting local guys always ended up with them insisting that they fit a new section, to make it worth their while. I gave up and bought scaffolding......
I renewed my licence a few months back, taking the Thai version of the online test which had videos of a couple of Thai lads explaining the obvious - there were English subs. The answers to questions after each video were really obvious having paid attention and using google translate. I didn't get any wrong, but a wrong answer would have been indicated.
Has the test changed recently from the two guys more interested in eating than getting started and showing poor driving such as only one hand on the wheel and turning to chat with the passenger?
If you are a farang kee nok, you can do as I did and DIY.
