@Gala: Its not that simple though.

The fact is that hes using some kind of weapon and is threatening your life or your car. Supposedly, nothing happens to you if you give up the car...but you cant know that.

I guess there are obvious signs like if hes got mental health problems or you notice the gun is actually a stapler, but outside that i think itd be really difficult to rationalize that the car is his true goal and not something else.

If i was armed, i think id be looking for any moment that i could 'safely' draw and fire. My life is already in danger imo.

Lets not turn this into a "value of human life discussion" thread though. We've had that already! (PS, i push the button that randomly kills for small sums of money...and id kill for less if it was a car jacker).
