This is great video to study on many levels beyond self-driving car. Some observations:
* The car behind didn't show turn signal so probably driver wasn't paying attention.
* A small car escaping with not too much damage while SUV rolls over many times
* From physics point of view, the car behind produced almost perfect torque that started horizontal spin on SUV
* Collisions with barrier at high speed can produce lots of rolls. Many time we see cars upside down in accident and wonder how did that happened. This is how.
* The middle barrier did its job wonderfully even against massive inertia of SUV. Cars on other side remained unscathed!
