It seems to me to be highly unlikely that they only shot video of three of the four vehicles crossing the Pascoe, so Canny could immediately dispel the water ingress suggestions by posting footage of the failed vehicle doing the crossing. Unless, of course, the footage clearly shows it dunking its air intake, and unless the footage has mysteriously ceased to exist.
The very fact that the footage hasn't surfaced is to my mind compelling supporting evidence for the "drowned" theory.
