I'm pretty paranoid about battery fires. I store all my 18650s in vented metal ammo boxes, generally don't leave devices charging while I'm out of the house, etc, but I would hope (and I assume) something as large as a car battery would have a large safety margin built in.

I had a nightmare where all the lithium batteries in the USA were intentionally booby-trapped in their manufactury so that a preset radio signal would cause them to burst into flames! Something to do with China vs USA conflict over Taiwan. So I had to run around taking out all the batteries.

I think that's paranoid!8-)
