What if Victor had not gotten Margie and Luke to Uturn Amanda and Kris?
What if Amanda and Kris had not been Auto Uturned in TAR18?
What if Tammy and Victor did not Uturn Kisha and Jen? = Bathroom break and taxis don't matter?
All good questions!
Amanda & Kris were such strong competitors that they could've made it very far on both seasons, if it hadn't been for those U-Turns. How far exactly, it is hard to predict.
As for the Kisha & Jen U-Turn - they definitely would've survived, assuming that 'Chinese Waiter' Detour took a fair bit of time.
I don't remember Victor being the reason Amanda and Kris were U-TURNed. I am very sure Margie and Luke wanted to get rid of a stronger team. With such strong teams in TAR 14.. I'm not sure if Amanda and Kris would have made it further than F7.. but I'm pretty sure they will win at least a leg... not sure if they will win because the teams were really strong in SEASON 14.
If Amanda and Kris were not auto U-TURNed, Ronald and Christina will be the first team eliminated. (Pretty sure, unless they really suck at directions to the pitstop) Which I'll loathe as I like Ron and Chris. Again, I'm not very sure if they will make it far.. because people keep deeming them as a strong team but look, they fell far behind enough to be U-TURNed by Margie and Luke, they solved the starting line clue last, reached the first pit-stop in second only to lose the lead because they couldn't find the sign-up list and ended up on the 2nd departure time. Let's just say their luck either sucks or they're not good racers after all.
Again, the U-TURN is too far in front of the episode to decide whether they will survive. I think they might, but they were actually before Jaime and Cara at the Roadblock anyway and still lost their lead.
