I was considering the first column, which does list Thailand as second highest in terms of road fatalities per 100k inhabitants. By second column, I didn't mean to say skip the column with country names -- that may be the mixup. Here's the source data too: http://www.who.int/violence_injury_prevention/road_safety_st.... I think considering the number of road fatalities and accounting for population seems like a good enough comparative measure.
If you looked at the page, the road fatalities per 100,000 motor vehicles ranks Thailand somewhere in the middle out of all countries.
