LFP Battery hazards vs NMC/NCA
Source:
- There are "fillers" between cells that are endothermic, heat absorbing. This reduces the risk of a complete pack event.
- There are "separators" within the cells that upon heating, block ion transfer, turning off energy release by the cell.
- As for relative risks:
  
  NMC/NCA - heat and fire
  
  LFP - toxic gas with a lot of explosive hydrogen
I am leaning towards battery pack safety regulation that incorporates both the "filler" around the cells and "separators" within the cells. Not something that needs to be done instantly and should not specific the specific media. Rather, a performance based, benchmarked solution.

Lucid Gravity - wow!

Very impressed with Lucid Gravity designs. Pricey but very nice. With adjustable suspensions for off-roading. If only they have solid states, lfp or sodum ions. Still on lithium ions.
