I ride often in Thailand and over there the driving test is seriously, a joke. For instance, you have to give way to vehicles joining a roundabout, rather than those already on it. So the roundabout is always choc a block and fortune favours the brave. Indicators are just pretty lights on the car and can be any colour you can think of. Motorbikes aren't allowed on a motorway, however you will often see the small 125s buzzing along the equivalent of the hard shoulder. They will drive in any lane and under/overtake at will and funnily enough, it's accepted! I now have an understanding why you often see someone who is probably used to driving overseas, shall I say, driving in a middle lane, as that's what they are used to in their home country and can't understand why it pisses us off so much!
If you are the first vehicle stopped at a traffic light, you will suddenly find yourself surrounded by @ 20-30 small bikes all around you and sometimes the lights will change to red before you get a chance to move!
Funnily enough, I thoroughly enjoy riding over there - now I'm used to the 'Thai' way!
