That is kind of my point.
During COVID, I delivered food (4500 deliveries), because the drilling end of the oil patch here had come to a standstill (first time the rig count hit zero since the 50s, when oil was discovered here), and before and after COVID I did wellsite work.
I had an occasion to slam on the brakes to avoid hitting some idiot that could not understand that right turn on red meant when the way was clear of oncoming traffic (namely, me).
That's pretty much what the pizzas looked like when the delivery bag hit the back seat and ended up on end on the floor. They were still in the boxes, but mostly in one end of the box.
If all 8 slices were there, the distortion is likely due to either sudden deceleration or just being dropped on end.
