Hi Mike
It appears unlikely that the sand dune has moved much , as it would be blown in the direction of the car as per the photo's and the car is still mostly uncovered.
His description was that he "rolled off the crest of a dune" , so he didn't go over it at right angles.
The main picture certainly supports the above in that he went at an angle along the edge and the soft sand just pushed out and away from him.
In the picture the trailing edge of the sand dune isn't even that steep or
that deep really and this is after the blow.
The physics of the car then just took it down.
It a natural reaction to take one's foot off accelerator just at that point which then causes a twisting momentum just when you don't want it, whereas , some acceleration may have helped , but usually that type of car also has little scope for quick acceleration.
He is relatively local here so hope to get more info yet.
