I can't believe people are actually going with the cybersecurity angle here. Sure, in some super rare edge cases, there are probably circuits that could be hacked and overloaded to cause the Lithium-Ion batter powering it to combust. But Lithium-Ion batteries don't explode. They combust over the course of a couple of second to minutes. Not to mention, even if batteries did explode, which they don't, we're talking a single triple A battery not an EV cell.
