Wood actually has some properties that make it desirable in a fire: the charring creates a natural barrier and it doesn't melt meaning it holds structural integrity. This makes it very desirable for building construction, but for cars it means it can act as a fire barrier potentially, and save lives.

EVs are 10x less flammable than ICEs, so the wood would help bridge the gap.

Are you sure EV batteries are less flammable than diesel?
