Some people started setting cars on fire in a number of neighborhoods randomly in my city the last few weeks during the night. One of these fires happened next to my bedroom. First car was traditional ICE but the second car was hybrid and water was useless on it. The firefighters came up with a second truck and stopped the battery fire using a special foam.

Interesting note, the fire was propagating from the back to the floor - where I imagine most of the batteries lies - to the front engine bay but never burned in the cockpit area. I guess those battery equipped cars have some additionnal isolation to protect the passengers.
