I saw the same thing in Ghana. On several occasions, the traffic light in the town’s busiest intersection would fail for hours, usually due to a “dum-sor” power supply shortage in the region[1]. However, all the drivers were very experienced with 4+-way intersections with no lights or signage, and everything progressed pretty smoothly (until I had to make my way through).
