In the thread about using car doors for cover, it was (rightly) pointed out that the best use of a car is to exit the kill zone. But don't fall into "I must solve the problem with my gun!" If deadly force is justified, any deadly force is justified. Hit them with your car, a frying pan, stab them with your pen, use what you have.
Shooters tend to think that all defensive problems must be solved with their gun. Not so! If a fire extinguisher is closer than my gun, they are going to get the contents and then they get to wear the container for a hat! If I have a pen in my hand, I'll stab them with it!
To paraphrase General Patton, 'A good plan executed now is better than the perfect plan executed later".
Even in that TSA planned "sanctuary" of air travel you are surrounded by potential tools to use in your defense. So keep your eyes open and your head in the game - you don't 'have' to use your gun!
