Fortuner going sideways in snow

I was watchin the youtube videos Tal posted from their All out Africa trip and came across this video of a Fortuner going sideways.

http://youtu.be/oNAK6Nns8Vg

The people filming the event mocks the Fortuner a bit, which may not be fair if its due to driver error.

I thought I read somewhere that modern 4x4's with stability control systems engaged, may have a tendency to bog down in thick soft sand. Could this be the reason for the sideways maneuvres in the Lesotho snow?

I'm keen to get some expert views on this, as I don't believe its due to the Fortuner's abilities only, but just not sure.
Regrets? I've had a few...but then again, too few to mention.

The same will happen in sand! Its due to inexperience!!!
What to do when you want to change tracks in san and snow:
Use a bit more power with a very direct turn of the steering so that the front wheels shift the sand and move to the other tracks! The rear will follow! However if you turn slow with no power you will either push sand or snow forward with front tyres and get stuck cause you will start spinning! Or like this guy your front will go into the tracks and rear will stay behind and itll start sliding like that!
Tyres would also have made a huge difference here! A MT would grab the snow and just get over, they were talking about "pad tyres", pad tyres will just pack with snow and you would have zero traction, basically riding on slicks!
Hope this makes sense!
I think his TC was turned of, or driving in LR, which anyway means TC is of!

Using H in sand youll have to turn of the TC, cause if not, it will cause the vehicle to lose power and momentum and thats all you need in sand is momentum!

That looks like he is driving with rear diff lock engaged.

I have played in dune sand and that sort of loss of response from the vehicle only comes from rear diff lock on uneven shifting surface like soft sand or snow.

Great, thanks for your views thus far.

I agree that HT tyres would not be as good in snow, yet still felt there was more to it.

So, correct technique and no rear diff-lock for these conditions in addition to the correct tyres.

Difflock wasnt wrong if he was in his line, then difflock wouldve helped, depends on conditions! I think its more a case of knowing your vehicle, if you use difflock, turn of before you turn cause it'll make you dig in or keep pushing the front wheels straight

If its a level surface yea but as soon as there is camber, the outer wheel will irrespective of traction continue to rotate equal to the opposite wheel and erode the outer edge, opening more space for lateral movement? I can drive along a dune at a low aide angle in 4llc no dlock and have minor tail slide. Add diff lock and tail drops like a weight in water, same as it did on the video. No matter how much right foot and rapid counter steer, the outer rear wheel will always drag you down because its eating away at the lower support all the time. Thats my 2c

I woulf be happier if the TC could be shut off in HLc. Those Christmas lights and alarms are about a entertaining as Eskom.

We have been there 3 times during winter. Very unpredictable. No snow to being completely trapped.

Fantastic experience but the Chinese are improving the roads too much!
