The mechanism of ignition would be interesting to know. The first thing I thought of when media claimed that the batteries were disconnected for transport was that a vehicle with a disconnected battery is not a normal condition. How is it disconnected? (vision of terminalled cable flailing around under bonnet.

Normal condition is with battery connected (and charged). Cars in normal condition are, I suggest, less likely to ignite than cars that are not, for whatever reason, in normal condition.

I am minded of a feeder that almost re-ignited on Nordfarer during clear-up after a collision and various mayhems in the Channel. The (fire alarm) battery did not have enough current capacity to melt the short circuit protection covering a fault but did have enough to start cooking the conductors. In a conventional vehicle the starter circuit will not have short circuit protection but I imagine an electric vehicle does (anyone?). Not implying this was the cause here but one example of a, perhaps, counterintuitive consequence.

Pleased everybody safe. Unlike the Grimaldi ferry fire - fingers crossed for more survivors.
