Excluding collisions, I don't know about the 10x, but I'll bet most of those were older un-maintained ICE, loose fittings, gas leaks, sparked oil fires on an engine. Not explosive batteries like some of the EV early on, nor spontaneous combusion of the entire power source.
My point, generally remains, when we capture heat and make it 'user consumable', as in transportation, tools - a welder for example - or other compressed combustables, we will have failures. So, no matter which choice we make, ICE, EV, Hydrogyn, we have risk, and we need safety procedures, safety equippment, and training to understand those risks.
We cannot choose one over the others and claim it's safer. At this point in technology and engineering, we have no clear winner when we store a power source, and convert it into 'work'. I'll be the first to admit, and applaud the ongoing efforts toward safety and efficiency. But we are not there yet ...
