They brought back the Yield, the worst iteration of the time wasting obstacle, but at least the 10 and 20 minute variance and how they got them was somewhat interesting.
Sharing or not sharing info has been around almost since the beginning of TAR. I don't begrudge any of the teams in back for how they handled themselves. Any of them could have read the clue more carefully. I was bummed that there didn't seem to be much chance of places changing from leaving the final task, but we have seen teams just miss Phil when he's standing right in front of them before.
The Olympians mostly seemed done in by taxi luck, even though they could speak Spanish. That does bring to mind a previous season's winners Nat & Kat, the anesthesiologists. I remember them saying in an interview they spent time at the start of each new city vetting their cab driver if they rode a cab, to make sure they could communicate with them and that they seemed to know what they were doing. I think most teams in TAR's history just jump into the first available cab.
