Forcibly removed from vehicle

Assume that we are under Texan law. For the scenarios I would like to know at what point would you be able to draw. Also answer for both nighttime as well as daytime if possible. Scenario 1: You are sitting at a stop light awaiting green. A man approaches from the driver's side of the vehicle no weapons are visible; he opens the door and without verbal communication he begins to pull you from the vehicle. Scenario 2: Sitting at a stop light awaiting green. Man approaches with no weapon, opens the door; but he makes a verbal statement or request "I'm taking this car" or "Yo give me your car"; he then begins to pull you from the vehicle. Scenario 3: Sitting at a stop light awaiting green. Man approaches with a visible weapon and opens the vehicle door making a verbal statement that he intends to take it while also attempting to remove you. via /r/CCW http://ift.tt/2CdXulL
