If you say "well, I thought he was reaching for a gun," that does not exactly put your life in danger...especially if he wasn't. Lying in court is another felony, so you are just setting yourself up for disaster. A car is not worth risking my life; if the person broke into my house where family and friends live, that is different, but a car (unless of course, I am in it) is not something I would confront AND kill someone over unless they pulled a gun on me first. And no, it is not the worst analogy...it is just as stupid as the question the OP posted, and that was the point.
