Normal vs complex roundabouts
Waze supports two different styles of roundabout navigation instructions. One style instructs simply to turn or continue at the roundabout, while the other instructs how many exits one must pass before leaving the roundabout. The US editing community terms these two instruction styles as "normal" and "non-normal" respectively. The term "normal" is used here in its mathematical sense to mean "orthogonal", "perpendicular", or "at right angles".
