Avoiding traffic accidents in the tropics

It is now July and the hottest month of the year in Finland. I saw today some roadside advertisements in town area about traffic accidents in the world. The persons in the pictures looked very foreign, maybe from Cribia, and very borne to accidents, kind of attention lacking and too stuck ways without regard for their limitations. It is said that there are lots of accidents in the tropics. I guess that there are big differencies between countries and between areas in the tropics too about how much accidents they cause. For example Brasilians, some Arabs and Indians appear skilled: could one pick such peole to advertisements about traffic safety?
