Why are there only 2 girls on a bobsleigh?

In bobsleigh, teams typically consist of two or four athletes, and the two-person format features one pilot and one brakeman. The pilot steers the sled while the brakeman helps with speed and stability. The two-person team is designed for efficiency and speed, making it a popular format in competitions. Additionally, the limited number of participants per sled allows for more streamlined training and competition logistics.
