Things get really interesting when there are intersections of multilane highways. For example, an intersection of two 6-lane (3 each way) highways.
With 12 lanes of cars constantly approaching the intersection, that's a lot to keep track of to figure out who goes first.
I saw this recently with Irma in FL. Mostly each set of lanes would start moving roughly together once one person got brave enough to enter the intersection. But it's very hard to adjust to.
I even found myself sometimes just going after stopping without fully checking to see if I had the right-of-way or not.
