In many states, a simple wreck of a conventional car, which results in a cracked standard car battery, requires a Firefighter hazmat team to come do a proper cleanup. This makes any cracked battery minor wreck cause huge traffic delays.

Within this context, we can imagine the massively scaled up potential issues. The fire depicted above isn't just a dangerous mess, it is a ecological, climate, and hazardous materials disaster, all by its self. Schools and business would need to cancel for blocks due to poisonous fumes, for instance.
