Nah bro this is down to the lithium chemistry of the batteries.

Current recommendations in some places is to park buses farther apart to limit spread, because if they are near each other like this, the batteries burn so hot they catch the next-door neighbour bus on fire too.

Ok. But are you sure that the engineers contained the electronics controlling the currents inside the bus "reasonably" secure away from the batteries ?

You don't understand. Lithium-ion batteries, with a few exceptional chemistries to the contrary, are all bombs ticking, waiting to go off at an unpredictable time. Overheat starts the fuse. Overcharging or overdischarging starts the fuse. Damage starts the fuse. Sometimes, for no apparent reason at all, they go off.

    LeFePo4 is not used because they can't give the same power. You're looking at twice the power of lead-acid for like ten times the up-front cost. It absolutely is the chemistry to use in a mobile environment, from a safety standpoint.
