By reading the title I was expecting a totally different kind of content.
I believe the ALF guidelines about safety are more relevant and apply in this case as well. I don't remember the exact phrasing they used but the essence was this:

In this conversation about EV cars, it is especially important to think of safety, because their batteries have the nasty habit of exploding in uncharted yet ways. If I remember correctly ELF following the ALF guidelines in one of their actions before burning down a building, they moved a gas tank a few blocks away so that the firefighters that would come to extinguish the fire would not get hurt by a late explosion. That is safe, and nothing less is good enough, at least that's how I see things.
