Pretend you are driving to work, or dropping the kids off at school. It’s 7:45 in the morning, one of the busiest traffic times of the day. You are waiting your turn in line at a four-way intersection controlled by stop signs. It seems like it is taking forever to get through the intersection. Finally, you get to the front of the line and there are a total of seven cars waiting to cross the intersection. Four cars plan on going straight and three cars are making left turns. Can you see it? The confusion?
