Oh no.
Also yes totally buy an extinguisher. I have one. And if for some reason your country/state does not mandate a road kit with an extinguisher, also get one + a First Aid Kit for your car. Also buy a First Aid Kit for your house. Also fill it with Tourniquets. Your car too. And a couple flares. And some light sticks. And a couple flashlights and keep them charged. And some emergency food and water.
