I think the team that fights over sungalsses in Adam and Rebecca becuase in the first epsidoe they already faught over the glasses she got amd and said "Sungallses are not conducsive for fog" when he put them on in Iceland. And i read on another sight with a interview from Mirna that you are allowed to take locals with you in a car they just cant drive. And i dont think its Meri and Maria becuase it shows them in the commercial finally going at a normal speed with Maria drving. I think the team that gets a penalty is not on the commercial so i think its either MJ and Don, Hayden and Aaron, Adam and and Rebecca, Kris and Jon, or Lena and Kristy. But maybe Lori and Bolo.
And someone said something about people not knowing about drving stick before going on the race. Threre were alot of people in past seasons who could not drvie stick, i know Will at the top of my head, and Heather or Eve.
And it looked like Gus and Hera had no prob with the roadblock and Kendra is having a lot of trouble. Then i would guess that the detour would be those boats b/c thats the only physically demanding thing, and i would guess that zip-line in Norway everyone would have to do it, like how everyone had to go down that hill in leg 2 of AR4.
