So one small battery on your head is scary. What happens if this happens in an electric car where you are sitting on a huge bank of batteries?
You get out of the car.
They don’t tend to explode like in an action movie.
Like any of dozens and dozens of things, they might burn down your house albeit quite rarely.
People really need to start accepting that risk is never zero.
Not always.
Electric cars are also quite dangerous for firefighters to put the flames out (you can't use water for instance and it's even more dangerous in rain) and since they are relatively new not all firefighters know how to extinct them properly.
I worry about this too. Cripes!
