The relationship that matters here is the relative speeds of the vehicle and the bullet. The vehicle speed remains constant, but the the bullet slows from the moment it leaves the gun. The bullet, in your example, has an initial velocity over 10 time that of the car. Long before it slows below the speed of the car it's trajectory has taken it out of the cars path. But a bullet fired from an aircraft going supersonic may initially be only twice as fast as the plane. It's speed will slow to that of the plane much sooner, and in some cases allow the plane to catch up before the bullet 'drops' out of the planes path.
