Why don't pro caddies use buggies?

Pro caddies typically do not use buggies because walking the course allows them to maintain a closer connection with the player and the game. This proximity enables them to provide real-time advice, read the greens, and assess course conditions more effectively. Additionally, walking fosters a deeper understanding of the course, which is crucial for strategy and shot selection. Lastly, the tradition of walking in Golf is deeply ingrained in the sport's culture.
