  For conventional cars you might still have a chance to put out the fire using fire extinguishers as the highly combustive materials, mainly fuels, are actually contained and they will not be a problem until vital structures compromised and such deterioration can be avoided by routine services. But there is not much you can do for Li-Ion batteries. Lithium spikes grow each time you charge the battery and eventually those spikes will penetrate membrane between electrodes, beyond which point the explosion will be inevitable: the process needs no air and will not stop until energy stored in the cell fully discharged. For small batteries we can prevent situation from deteriorating by putting them in water. But there is not much can be done for the size in a Tesla. I've seen video footages of two accidently involving those, one was a couple of years ago in the car park of a Shanghai apartment. Started with just a little bit smoke, but in just around 10 seconds, the Tesla was beyond redemption. Luckily there was no casualties. The other one was a tragedy. A guy brought a e-bike in to a lift and just when the lift door was about to close the battery started to burn. Unfortunately they missed the vital second that could stopped the lift door from closing. It turned several people severely burnt, including a baby.
