What does a co-pilot do in a rally?

As a rally enthusiast, I've always been curious about the role of a co-pilot in a rally race. A co-pilot, also known as a navigator or co-driver, plays a crucial role in guiding the driver through the course by providing precise instructions on the route, the upcoming turns, and any obstacles ahead. They also help the driver maintain the correct pace and manage the car's performance, ensuring the team stays competitive throughout the race. The co-pilot is responsible for reading the pace notes, which are detailed descriptions of the route, and communicating them to the driver in real-time. In summary, a co-pilot's essential job is to ensure the driver has all the necessary information to navigate the rally course efficiently and safely.
