In both cases it's an absolutely massive thermal conflagration, with no hope of putting it out using anything a homeowner has on hand, and it will proceed so rapidly that the house is going to be totaled by the time the fire department shows up.
I have to figure this is just bias toward the familiar. I will grant you that I don't refill an ICE car inside my own garage, so maybe charging genuinely makes the electric more dangerous. But it probably doesn't do so in fact, I would guess in both cases the biggest risk is something like leaving rags soaked in linseed oil and getting spontaneous combustion.

A sprinkler system running on regular water supply pressure is not going to put out a lithium ion fire.

Those are 2 big states in there. By population the four are ~73 million, or a fifth of America.
I mean, it's also true that water will not put out a gasoline fire, only spread it around and make it worse.
But what you said is true also.
- 47% mechanical
- 21% electrical
- 7% intentional
- 6% exposure
- 4% crash, overturn, run-over
- 2% smoking
So crashes are a relatively rare cause. They also break it down by the area the fire started:
- 63% engine area, running gear, or wheel area
- 11% passenger/operator area
- 5% cargo/trunk
- 3% exterior
- 2% fuel tank or line
Interpolating between those numbers, you might guess that between 20% and 40% of fires could be described as "engine spontaneously combusting." That would be 45,000 - 90,000 per year in the US.
So despite you never having heard of it, it does happen.

Most interesting is that the first part of an ICE to catch on fire is most frequently the electrical wiring. And even if it is a flammable liquid (the second most likely cause), it's only a 42% chance that liquid was gasoline!
Thanks again, it's interesting reading.
He noticed significant tingling in his feet while pushing the car out. This was in the days before GFCIs. He's lucky he wasn't electrocuted.
It'd been parked for an hour or two, and the trigger was something electrical in the engine cavity.

ICE vehicles can have strange failure modes leaking flammable fluids places where they should go where its really hot. Sometimes this gets mixed with a spark from a bad electrical connector, sometimes it drips on something hot.
It's definitely good to spread the awareness that many fire extinguishers are not suitable to put out lithium fires, though.
Only Class D fire extinguishers can put out lithium metal fires. But lithium-ion batteries do not contain lithium metal. Lithium metal batteries do so, but no EV uses lithium metal batteries because they're too dangerous. Class B fire extinguishers work just fine on lithium-ion battery fires. The difficulty with lithium-ion EV fires is that they tend to re-light, but water is still the tool of choice for putting them out.
But when I'm filling up my car with a jerry can, I'm literally holding it. I know to have some sense of caution, and I can see spills. I do not leave it to slowly trickle fill overnight, like one would with an EV; not only am I not there in that scenario, but odds are I'm not even awake.
The odds are minuscule, and you're more likely to die in many other ways. But the fix is so easy - assuming it's not going to hit -30, just keep it outside. And the risk (probability multiplied by chances for it to happen) is going to get so great when everyone has an EV, that I can at least see your point.
I don't agree, and were I able to afford a house with a garage and a Tesla to park in it, I probably would. Doubly so as it hits -50 with wind chill here. But to dismiss your concerns outright doesn't feel quite right to me.
This is true, but you can't see the static electrical charge on the can that's going to discharge with a spark when it touches the filler tube...
The reason you see issues in cases like this is because the wreck totally decimated that isolation with mechanical force and so you get runaway effects.
I mean that’s fine if this is the hill you want to die on, but right now I think it’s just as likely your gas car fireball explodes like a Hollywood movie while parked in your garage.
Maybe a quick search would help you find the answer for yourself before making such comment.
See for instance this article compiling a couple examples: https://www.thedrive.com/news/28420/parked-teslas-keep-catch...
Some of the occurrences are while the vehicle is being charged, some are simply when the car is parked.
