Maybe the fact the forest is dry from lack of rain and heat has more to do with it than the ignition source. As we've seen in the US, when forests are in that condition fires are pretty much going to happen. If not an EV, then an errant spark from a camp fire, or from electric lines, or lightning, or even from someone dropping a lit cigarette, will start a conflagration. It sounds like the problem might be more lack of forest management than EVs. Sometimes you have to selectively thin forests to keep the entire thing from burning down.
