Far more than 20,000 pa road deaths in thailand im afraid, only deaths at the scene of the accident are counted as road fatalities, so reliably you can guess more like 30,000 road
fatalities. Now also consider that 80% of road deaths are motorcycle and pedestrian, I'll let you do the math.
There is a double headed demon here and the Government belongs to both, no road danger or skills education and no Police that actually serve the road users safety.
Sadly I dont believe that either will ever change, as the people in power have only 1 ambition, personal financial gain
