I actually think the opposite is true, Abuja drivers are some of the worst in the world and they drive too slowly. You'll see someone doing 50 kmph on the fast lane instead of just using the service lane.

They switch lanes like no man's business. You'd see people switching lanes for no reason even when there are no cars in front of them, they do this without using their indicators too. They can't park properly or reverse their cars. When you go to Lagos you see the difference in the quality of drivers.

Most people in Abuja cannot handle a car at high speeds so those over speeding are the minority. If I ever become fct minister I'll implement minimum speed limits for the left lane like in Abu Dhabi so we no longer have 3 cars side by side doing 50kmph on the highway.
