FWIW, speaking with a buddy of mine in the car service business, he sees they see a good number of the EVs that come in for issues have physical damage to the undercarriage/ chassis that contains the battery assembly.
Somehow the owners are running over curbs, debris, speed bumps, dunno ... and having compromised the ‘cage’ protecting the batteries, if the physical batteries inside are damaged, the electrolyte of the batteries can readily ignite when exposed to air and heat-of-charging.

Makes sense.
They’re trying for the least aero drag, so the cars sit low.
Also Teslas have had a lot of problems with cast aluminum suspension links failing and they drag bottom.
Great. Cars are designed to ride low to the ground for aerodynamic reasons. The battery, being heavy, is mountrd low and thus vulnerable to road damage. Brilliant. Simply brilliant.

Interesting post—if the under-carriage is low to the ground that would certainly increase the risk.
