Who cares where suicidal drivers come from? It won't make any difference to me who kills me or my family. The only difference is that foreigners will be punished and locals won't.
And although I tend to agree with Terramax on many points, I do believe it's mostly local people who put others in danger with their driving. Yes buses and trucks are dangerous enough, but it's landcruisers with young local guys behind the wheel that fly at breakneck speed with no consideration of traffic rules or other motorists.
