You seem to be under the common misconception that it's the energy density of batteries that make them unsafe. This is completely false. There's nothing inherent about battery energy density that makes them more dangerous. What makes LiPo/Li-ion unsafe is that they have a flammable liquid electrolyte in the middle, that's both responsible for starting the fire (the explosion you see with some battery fires) and for failing to keep the anode/cathode separated afterwards.

LiFePo doesn't have significantly less energy density, but they're far safer. Same with sodium batteries. Solid state lithium ion batteries have more energy density than Li-Ion/LiPo in some cases, but are generally far more safe, since there's no flammable electrolyte.

EVs, even with LiPo/Li-ion, are FAR safer than ICE vehicles, there's just no competition. Lots of oil and gasoline being piped around, with potential for leaks + old electrical wiring = recipe for disaster. We had a huge parking garage fire here in Norway recently, started - as they often do - by an ICE vehicle. Lots of EVs in the garage, but not a SINGLE EV battery pack caught fire. If all of them were EVs, the fire would be far less serious (the interior of the cars still burned, but that's all).

EV battery fires are tricky to extinguish, I'll give you that. But the fire department here in Norway say they already have the needed training/experience, and make it clear that EVs are far better for fire safety in general.

As for your points on whether they're better for longer distance, personal journeys.. I mean, yeah.. at some point they are. If you're driving 1000km in a day I'd definitely agree. But how many people do that often?

* far higher energy density: don't forget to account for efficiency and regenerative breaking (hybrids get some of that benefit, but then you get all the downsides of both technologies) .. practical range difference is much closer than what your numbers would indicate. For most people the range of EVs is good enough, even for long trips.

* essentially immediate "recharge" time: Yeah, but it's still a couple of minutes and you have to stand there while it's filling. Almost every single road-trip charging session for me has been: 1. spend 30 seconds plugging in and beeping the payment card (with Tesla you don't even have to do this). 2. walk into a restaurant/cafe/grocery store and take a pee, drink some coffee, buy groceries for the trip, etc.. 3. come back to a fully charged car

* 100+ years of ICE drivetrain expertise: This is totally pointless. The only reason you need that expertise with ICE drivetrain is because it's so hard to maintain. Most EVs simply don't have anything to maintain, other than what all cars have (break pads, air filters, etc.). And I've never heard anyone here in Norway having trouble getting their EV fixed due to inexperience. The training isn't hard. You can even get people to change individual battery cells on some cars now.

* The last point I covered above.
