In this little story, the question being asked is: “How could this happen?”
“This” being this:
To me, the answer seems quite simple: the Audi used the McLaren as a ramp — or a partial ramp, mounting it with only the right-hand wheels, which caused it to flip over onto its side. (The low-profile front of the McLaren, by the way, seems to make for quite an effective ramp.)
The real question is: what would make the Audi’s driver go so fast in a supermarket parking lot as to turn a simple collision into a flip-over? Trying to get into the vacant spot next to the McLaren ahead of another car? Hitting the throttle instead of the brake pedal? Sexting on the iPhone? All of the above?
Truly, some people should not be allowed to drive on public roads.
