i'm not sure how this would of turned out if he was in a car. he had the ability to leave the area since he was in his car. however, if he was blocked in by traffic he might of been able to discharge his wepon and been under the "self defence" rule. i know in indiana, you have to prove that you had no other choice but to use your firearm. in this case, he was in a car and had a easy way to get away from this other nutball.
