I don't like mealy mouthed information, statements like "no definitive evidence" or 'the cause of the fire was never definitively determined". Such may be useful in court, but when it comes to this subject, we actually have quite a bit of information.
Of the 4 EV carrying ships that burned, all of them had captains, crew members, firefighters and journalists present who noted the fires started with the EV's. Statements like: "The fire started in the battery of an electric car,” "Smoke was first observed rising from a deck containing EVs" "seven EV's were already burning when firefighters arrived" are ignored by those who like to claim the EV's are not the proximate cause. They most certainly are the cause of these fires. In some cases we even know which EV.
Telling the truth doesn't help the agenda.
