Good info, and great points. Another factor to consider with the mounting is accessibility. If you have it zip tied and so secure that it delays getting the thing out when you need it, you might as well not carry one. Those extra few moments may mean the difference.<br><br>That said, I dont think I need to tell everyone that a car fire is extremely dangerous, and opening the hood will more often make the fire worse (more air), and that small extinguisher isnt going to do much for a full blown fire that will ensue by opening the hood. Most often the best bet is to just stop the car and run. I carry my extinguisher mostly for "other" incidents, and if my car catches on fire, most likely I'm running away. That's why I have car insurance.<br><br>
