Yeah..I know what you mean.The U-turn needs to be seriously revamped.
What I'd love to see is something that I saw suggested a few years back.
Have the Double U-Turn board designed with a touch screen. When the team gets there, they touch their picture, and it shows them whether or not they were u-turned. Then, they are given the option of u-turning another team. They get no other indication.
If the team they choose to U-turn is in front of them, the U-turn doesn't count, but the team is unaware of that.
That removes the ability of teams to conspire like they did this episode. A team will not know if the team ahead of them actually did U-turn someone like they were supposed to do, and they wouldn't be able to U-turn that team ahead of them to burn the U-turn.
