Many seasoned overlanders would agree that the biggest immediate danger presented to them comes not from violent crime, assault, malaria or vehicle theft but from other road users sharing that thin ribbon of (hopefully) unobstructed land.
This clearly defined interactive map shows the number of deaths per 100,000 population for most of the world’s countries. Grim I know but I think it could be useful. Stats can often get skewed with these things so its best to draw comparisons from your own experiences. From my experience Mali was probably the worst for careless driving alongside Kazakhstan which both rank in the low 20’s. However does this translate to the statistics shown? Linked to the map are a number of accounts from developing nations that I can personally attest to from Bamako, Mali and Jakarta in Indonesia. Let us know what you think from the places you have visited and driven in the comments.
