Laura we have speed limits. And traffic rules.
No one follows them unless there is a patrol car. People drive on the wrong side on highways, tuktuks pop out of no where.
Speed limits are 60-90kph (excludong expressways which are basically point to point roads connecting major cities, not common at all.) as far as I'm aware. Rural roads, we drive at 20-50 kph max, lots of people and animals that can pop out of nowhere.
As Andrew says, people drive a "bit" faster.
