I'd say the second occupant of the vehicle spent a full minute submerged unable to breathe while he fought to get his seat belt off .
Preparation equals windows down and belts off so at least you might escape the vehicle .
as evidenced by the eejit in the background jumping in and being swept away!!
One of the reasons I have rope on my winch rather than wire is so that for a dodgy winch or tether I can standby with a knife if it all goes tits.Not content with nearly drowning they then proceed to try and topple the jeep on top of them. Not to mention being in the firing line if the winch line broke.
I think having less of a suspension lift and being lower vehicles and way made it catch the water and float easier, no snorkel probably meant some water could’ve got in and caused it to stall.
They were very lucky indeed.
