I am pretty sure the cells are compartmentalized so I would assume what happened was a slow process of each compartment heating up to a threshold eventually cau

  Aren't batteries under the cabin floor though? That hot-swap demo from few months ago seemed to imply that they were.

    Yes, they are but I am saying the cells are in their own mini compartments. Think of like a ship has compartments to keep the entire thing from flooding if it is breached. At least that is how I have understood it to be. Obviously this doesn't prevent heat from spreading and could still have a runaway chain reaction like in this case but it does maybe give more time to warn you.

    They are, but they have heat vents that spew off into the front, to protect the cabin itself. That is why the front of the car caught fire. The battery itself is also segmented such that thermal runaway doesn't cause a cascade to the whole battery (which is why the driver here had ample time to continue driving and pull over).
