Considering the first part of that challenge is that they submerge the hilux in the sea, I can't see the tesla holding up too well. Would love to see it though!
I wouldn't be so sure.
While you obviously don't want to test it, there are videos of Model 3's and Model S's being driven through water over the windshield and were fine. IIRC there's a video somewhere of one of the Tesla models actually floating when the water got too deep.
