This appears to be the accepted view. I have tried unsuccessfully to find an online copy of the aerial view, as it is clearly more understandable than the earlier pictures, which showed no signs of tracks on the verge, or damage to the wall.
Car fails to turn into the left hand bend, and starts to cross the road in line with it's initial direction as it hit the ice.
Driver is trying to turn into the bend.
The driver sees the cyclists, and has already failed to turn to the left, and so attempts to steer to the right, which starts to present the passenger side of the car to the cyclists, as it turns broadside on.
Car strikes cyclists, as the car continues ontowards the verge, (and driver puts left lock on to try and avoid the wall) the grass is soft, and the wheels finally achieve some (still very little) grip, glances into the wall, with the
drivers wing striking the wall.
Front end is directed along the wall, and with left lock the front end pulls out and the car veers across the road coming to rest on the far side.
This is clear from the aerial view, as you can see the car tracks across the verge in a single two stripe shallow arc, which is directed towards the car at rest, and kisses the wall, just beyond the pile of bikes, and just before the bush you can see in the video.
The video shows a piece of spoiler/bumper against the wall. The policemen standing by it mask the scar on the wall, but there appears to be a piece of concrete leaned up next to them.
Somebody posted that the Telegraph had the aerial view, maybe they still have it?
Meanwhile, this shot shows the damage to the passenger side which I believe was the result of impact of the bikes and riders.
Incidentally the verge looks plenty wide enough to incorporate a cycle path! All it takes is money and incentive!
