Lithium+ batteries carry lots of energy, and can be dangerous if abused. It's not clear if end-of-life petrol/Diesel cars were also involved in this blaze, but it is clear that, while offering many benefits, EVs have to be treated with respect.
Considering an electric bike but not sans taking precautions.

Massive BYD Fire: How Many EVs Burned?
Coffee (Team CW)Looks like safe (no thermal runaway) and performant sodium-ion batteries are finally on the way.

"The electrolyte experienced no thermal runaway, even at 300°C (572°F) or after nail-penetration tests."
Safer sodium battery eliminates thermal runaway with a heat-triggered polymer barrier
Some batteries have been known to catch fire or explode at high temperatures or when under stress. This safety concern has pushed researchers to experiment with different ways to design safer batteries that can ideally still perform reliably and efficiently. Sodium-ion batteries (NIBs) are considered a promising alternative to lithium-ion batteries, but still face safety risks, especially at high capacities. But now, a team of researchers in China has designed a new type of electrolyte for NIBs that may eliminate these risks, allowing for stable performance across a wide temperature range.
mazzoofound an old vid we did >10y ago.
we manipulated a single 18650 cell to bypass various safety mechanisms and overcharged it in a safety cage.
this is about the same energy and and energy density your phone has.
the size of the cell is a bit larger than your thumb.
