That looks quite uncomfortable. But newtogolf is right, slow people would still be slow. I've seen a foursome where both carts go ball by ball. Also the conversation in the cart after the hole or between shots when no one is hitting is an absolute time waster and a lot of high handicappers do it. I am somewhat patient but nothing gets to me like looking at a group in front of me and no one has hit a ball for 2+ minutes. Someone should be hitting AT ALL TIMES.
