Our Highway limit is 120 km/h but we wipe out 13 000 people per annum in road accidents here in South Africa ....which kinda rivals certain war-zone death tolls ! [Population = 54 million]
We have Speed-Averaging on Highways and Freeways via camera and still have the Traffic Police doing laser based camera speed checking from "hide-outs' along the road.
As to lane-culture: Its non-existent on our roads and the emergency shoulders often become speeding lanes of death-defying traffic.
From this past weekend in my area :
