text: Many companies such as BMW and Google have been working on developing driverless cars. While these cars have had some success on the road, there are some situations where a human driver is needed to take control of the situation. One example of this is a construction zone. Cars can have a radar and know how the road twists and turns, but in construction zones that is all thrown out the window. There are usually new boundaries created by traffic cones that the sensors on the car might not be able to connect.
