...While Tesla's NCA batteries are more likely to overheat and catch fire than other Li-ion chemistries, I don't see this as a major problem for them (yet). It's a straight trade-off between energy densities and thermal runaway risk...
Incinerated plaintiff's attorneys of course will attempt to convince juries that It's a straight trade-off between Tesla's profits and vehicle safety.
Yet another hazard posed by TSLA packs is that unlike gasoline tanks they are capable of not only self-ignition, but once damaged remain susceptible to re-ignition, until drained of energy:

Tesla battery reignites days after deadly crash...
MOUNTAIN VIEW, Calif. (KTVU) -
2 Investigates has uncovered new information about the deadly Tesla crash in Mountain View earlier this year along with a serious warning for all firefighters responding to electric vehicle crashes.
KTVU has obtained a 13-page safety alert written by Mountain View Fire Chief Juan Diaz, in which he highlights the dangers firefighters faced while responding to that wreck, including a high-voltage battery they had no way to stop.
Firefighters say they put the fire out in two minutes but soon discovered the battery fire in the electric vehicle would smolder for hours and reignite multiple times, even days later.
"The battery began to overheat even though we had already cooled the battery and it continued to reignite," said Diaz. "We don't have the tools to deal with a battery that is completely, basically destroyed.”
The problem, he says, was a lithium-ion battery that continued to flow with electricity after it was damaged in the high-speed crash, which the NTSB is still investigating...
The Mountain View Fire Department tells 2 Investigates the Tesla caught fire three to four times after the crash.
Diaz says it was only after the NTSB and Tesla de-energized the battery two weeks later that it was finally safe.
In the memo, shared with every fire department in the Bay Area, the fire chief also warns of another dangerous scenario firefighters could face: if a house catches fire with an electric vehicle parked at home, the damaged car battery could reignite later.
"If the battery is damaged, then we're going to have to basically monitor that vehicle for a prolonged (time) -- could be days -- to make sure it doesn't reignite," said Diaz...
