This couldn't be further from the truth. BEV fires get blown way out of proportion compared to ICE fires.

  They are far more serious than ICE fires, extremely hard to extinguish. Trapped, runaway energy is a serious issue that needs to be urgently addressed. (This comment is not some kind of X is better than Y argument, this is just a safety comment.

    Not trying to go for the comparison either here, but have you ever seen a diesel engine fail and go into runaway? It's pretty impressive if nothing else! https://www.youtube.com/watch?v=WvMl8LUzQnk https://www.youtube.com/watch?v=WvMl8LUzQnk

      When that happens more often than not the turbo seal is gone and the engine is running on its own oil rather than on the fuel it is supposed to be running on. When the engine oil runs out it will stop all by itself... Usually these are either scrap or ready for a complete rebuild (if you're lucky).

        Yep that's right. I've seen some pretty spectacular runaways with our big trucks on site, usually you just get on the phone to CAT and order a new engine lol

    This is only true for cars with lithium ion batteries that use a very flammable electrolyte. Cars that use lithium iron phosphate chemistry have considerably less exciting failures. And future chemistries will be even better.

      Is this getting better over time? What is the timeframe?
      - olivermarks 4y ago
        There isn't one. The idea batteries are getting 'safer' is not true and is not nearly an urgent enough issue.

        Why do you think that? It's totally wrong. LFP is absolutely being used already.
      - josephcsible 4y ago
        It's already started happening. The Model 3 SR has been using the safer LFP chemistry for about a year now.
