well, when i emailed WAAG they told me that it has no effect on airbag deployment because the sensors are accelerometer-based (ie. sudden deceleration caused by collision, etc.), and does not function via impact.
the argument that was posed to me by a colleague was that at front guard would cause greater damage to a unibody vehicle such as the rx300, unlike one with a ladder frame construction, such as the ML320, etc.
truth or myth?
