Again, talking about safety, not fires. Not only does number of fires not necessarily mean more dangerous: the fires could be on average smaller and/or easier to escape from, or maybe they tend to happen while unoccupied (block heater fires for example) etc. but also EVs could be more dangerous in other ways (they are heavier so maybe harder to avoid certain types of incidents?) so it’d be a wash even though they’re less likely to burn.

Additionally, rates are a better way of looking at these things I agree, but ignoring sample size and use case can miss part off the story. That might not be free case here, it’s just worth keeping in mind.
