Driving Directions Plague Several Teams, Determine Finish on 'Amazing Race' (VIDEO)

While you hate to see travel situations be the deciding factor on 'The Amazing Race' (Sun., 8PM ET on CBS), it's also frustrating when teams work hard to pull ahead and then an equalizer brings them all back even. Zac & Laurence pulled a very clever move at the airport, getting a much earlier flight, but it ultimately didn't matter.

!!SPOILER ALERT!!

Everyone equalized waiting for the next task to open for business -- well, except for Marcus & Amani, who got lazy at the airport and assumed no one was getting a flight the night before. Still, it was a tight race to the finish this week.

Cindy forced Ernie to U-Turn Bill & Cathi because she was determined to take first place. While it kind of made her look bad, it is a part of the game and legitimate to do. Bill & Cathi breezed through it and wound up in second place anyway. But to protect themselves, they almost randomly chose Zac & Laurence to U-Turn.

That move proved deadly, though Zac & Laurence were equally undone by driving off in the wrong direction. They weren't the only team that struggled with that this week, but they were the only team to seemingly get eliminated because of it. But they'd had a tough leg all along, starting with Zac struggling to learn dance steps while other teams passed them.
