In the Netherlands, firefighters demonstrated a very unconventional method for extinguishing a car fire. A burning BMW i8 coupe was thrown into a container filled with water and foam. 
No, this is not a staged trick, and the Dutch were not abusing any substances. The fact is that this method is recommended for extinguishing electrified vehicles. 
Recall that the BMW i8 sports car is a plug-in hybrid.
Immersion in such a bathtub is intended to prevent electric shock. 
Of course, the BMW coupe was extinguished quickly, but now it can be written off. The car is not only burned but also a drowned wreck, as paradoxical as it may sound.
