I just hope that the last example is just a mockup and a proper battery enclosure will be added at some point. I have been present in LiPo fires in e-cars; not fun.

It's not, and they're LiFePO4 cells. The sort you can drive a nail through.
The guy has documented the build process of the battery packs, and he did wind up destroying a few of the cells in various ways. None caught fire.
That said, I wouldn't endorse going *quite* that DIY / cheap. Pre-made packs are available which enclose the cells in a rigid plastic case. These are more commonly what you see stacked in large arrays in EVs.
Technology has certainly improved. If they can get the weight down to what the car had with its ICE and provide a range of 200 miles I can see this being a viable consideration. If U.S. gas prices reach what they are in Europe, I would think demand for EV conversion kits would go nuts. My other car is a plug-in hybrid with 30 miles of EV range. My job is 12 miles away so my RT is all electric if I wish. Charging this car at night with a 110v outlet costs me less than 38 cents.
Is that the video series where the guy has 3d-scanned the inner bits of the car to design the layout of the system? If so, quite impressive work.

I'm in a nearly ideal position for EV ownership. My daily commute is about 6-7 miles round trip, most of it at 15-20 MPH. On rare occasion, I have to drive downtown, which is a whopping 6 miles each way.
So range isn't an issue. 30 miles would be more than adequate. Ironically, it's hard to find pre-made LiFePO4 cells which have a low enough Ah rating that I could assemble a pack which is physically small while still providing adequate voltage.
My biggest challenges are lack of free time and, like most city-folk, lack of build space and charging capacity at home.
Yes they do make a 3d scan of the engine bay, trunk space, and for the transmission to help with mating it with an electric motor. Space would be my challenge as well.
