EV fires

and generally what RR said 

OMG OMG RANGE ANXIETY OMG WTF ONG I WOULD MUCH RATHER THE EARTH BROILED AND WE AND OUR CHILDREN ALL DROWNED IN A TOXIC CHEMICAL SOUP OF A SEA THAN I HAD TO PLAN MY JOURNEYS A BIT MORE CAREFULLY

"I think a few spicy EV fires would be preferable to catastrophic climate change, but you're all free to your own opinions. "

It takes 1 ev to light up to sink an entire vessel. See "Felicity Ace" incident. 

Still less deadly than hitting a bridge…

Also less destructive than the various car transporters that have sunk simply because the cargo wasn’t properly tied down.

Is a vessel sinking equal to or worse than catastrophic climate change? Maybe opinions vary on this. 

Only takes one vehicle of any kind breaking free of its lashings to sink a vessel.   Turns out that transporting large heavy items which are designed to move around independently is actually quite dangerous!

Indeed Coffers but a container of ping pong balls when it breaks free is rather less destructive than say a container load of lead rolls for roofing and that's why generally the latter goes at the bottom of the stack and the former at the top.  Unfortunately on a car transporter there aren't some light cars that you can put on an upper deck.  In addition when containers break free they tend to fall overboard rather than causing the ship to capsize because they're trapped inside it.
