Sure, once the truck’s on fire your kind of boned either way, the issue though is whether it might be easier for a lithium battery to catch fire than a tank of diesel.

And whether the battery pack is able to cope with the heat, how it affects the battery capacity, efficiency, longevity, etc. Even if it doesn’t catch fire, if your battery stops holding a charge after being around a big fire, that’s a pretty big issue for a fire truck.

Again, these kinds of issues aren’t secret, so I’m sure they think it’s something that can be worked around, mitigated, or maybe won’t even come into play at all
