The following two images are of a vehicle which rolled off the H1-7 just north of Babalala on the late afternoon of Saturday, February 18th, 2012. No elephant involved as far as I know (but that bottle of Savanna Cider may have something to do with the accident). Don't ask what that vehicle was doing there at that hour, or where it was going, I do not know.
This is pretty typical of what a vehicle looks like after it has flipped over several times (I should know, I have dealt with thousands of traffic accidents, so I have some expertise to base an opinion on).
The picture of the of the white Hyundai presents a different picture, so to speak. Note how the roof has been pushed way in, whilst the door frames on either side remain comparatively intact. Achieving such damage by simply rolling the car can really only be imagined if the vehicle bounces off something like a very large rock, roof first. Not many large rocks along the road verges in the Babalala area. Since the vehicle did not collide with anything on the road (which in any case would not cause the roof to be pushed in unless the car flipped first), elephant damage strikes me as a very plausible explanation. The tracks in the grass also seem to indicate that the car was pushed backwards off the road, which is consistent with the damage to the roof, which seems to be have inflicted from the front.
What caused the elephant to give the car a once-over is open to speculation, but what is not is the fact that Babalala is 39 or 40 km from Punda Maria. The only way to get there in half an hour is to drive at an average speed of 80 kph. "Average" means just that, so the driver must have exceeded 80 kph quite regularly for longer than just a minute or two.
Driving at such a speed at that time of day is completely insane, especially because the bush is thick for long stretches along both the H13-1 and the H1-7. (It is also, unfortunately, quite common in the north, but that's another story)
I await the full results of SANParks' investigation with bated breath!
