The clue is in the corner of the picture, my youngest is in the service and they will make a convertible out of a saloon in a few minutes if need be.
Its easy to say "to fast" but they could easily have been doing a legal speed, 70mph has become mundane , normal in a modern car and feel so safe and almost boring, but ive been in a car that was shunted whilst doing 70mph , we went sideways and hit the central barrier , bounced off , spun again and for a second time hit the barrier, it seemed to go on forever and was totally of control, the car was smashed on all four corners, all that whilst doing a legal speed.

They could have hit a ridge from what looks like a bridge they have gone over. We have similar on the A40 over the M5 and it is iffy on a motorbike at legal speeds if you hit it wrong. A woman spun out after hitting it a few years ago in her car and wrote it off.
The slip road rising up from the left to the back of the pic indicates a bridge under the motorway they have just passed over. The strip is the expansion joint. These can be a bit lumpyWhere are you seeing the bridge? Can't see it from the pics.
