I wouldn't be caught dead on a bicycle. Every time I see one I just want to run them over. Scooters and big bikes are the way to go. 

Very lucky cyclist, only inches away from getting his head smashed.  I have been on my bicycle several times in Pattaya but avoid the most congested roads.  Also cycling without a helmet is stupid.  

 

The first thing I did was to install mirrors on my electric bicycle, you need to be aware of any big trucks behind you at all times. 

Very lucky escape, hope he learned his lesson.
