>People say the same thing about Li-ion batteries yet they have proven to be significantly less likely to catch fire compared to ICE vehicles [1].

Isn't the nasty thing about lithium fires not how likely they are, but how difficult they are to put out, as well as how hot they burn?

Yep. Let it burn is currently the high bit of fire fighting protocol for EV fires used by local fire services.
It's only a matter of time before an EV catches fire after crashing into a building and a bunch of people die because the fire couldn't be put out.
20.7 million EVs were sold in 2025 alone. When is this going to happen exactly?
Is your argument that if it hasn't happened already then it can't happen?
Anything can happen, but you're predicting the future without any evidence. You just made up a scenario in your head, predicted it would come true, then you can't believe people would say it's ridiculous.

When was the last time this happened with a gas car? How often are fires happening with lithium iron phosphate?

You think a car is going to crashing into a building AND burst into flames AND be impossible to put out AND burn the building down?

When was the last time this happened? Let's think about odds and statistics super hard.

ICE car fires are easier to put out.

EVs catching on fire and then being impossible to put out is something that has already happened, and in fact as I understand it the latter invariably follows from the former. The only new thing that needs to happen is the fire happening while the car is not out on a road, but inside a building where it can set other things on fire. The fact that the vehicle cannot be put out and can frustrate firefighting and rescue efforts makes an already dangerous situation even more dangerous.

Which part of any of this is straining your imagination?

Wouldn't they just chain the burning car and pull it out of the building?
Anyone who thinks this should give it a try.
I'm not really sure what you think the difficulty is. A firefighter in fire protection gear hooks the burning car with a large metal chain, the other end goes to the fire truck, tow truck or winch, the car comes out of the building.

the heat of the car and the burning surroundings, and of course the toxic fumes.

No.
Yes.
