> Now imagine a lithium fire in a garage Much less scary than gas leaking, filling part of a large underground parking garage, then getting ignited and collapsing the entire multi-story residential building built on top of the garage. Also, while looking for examples, I learned that compressed gas (hydrogen, methane) is much less of a problem due to being lighter than air, so it doesn't accumulate as much, which means these cars are sometimes allowed. LPG, being heavier, sticks around near the ground also posing a suffocation risk.
