Given that these vans use LFP batteries (which have to reach extremely high temperatures to ignite) and they were not charging when they caught on fire, I'm very curious what caused the fires. We need more info.
I’m not so concerned about the Rivian batteries as I am the HEREBUYEVERGOOD schlock brand lithium batteries that Amazon sells. I see a scenario where a bunch of them spontaneously combusted and “melted down” into the drive batteries.
