Air bag deployment is a complicated issue. Being an ex-car parts supplier of actual air bag controllers, and learning much about them, a 200 pound "movable" object will likely never set off the airbags. The car is absorbing much of the energy (as seen by the photos), so the decel is not enough to constitute a deployable event! And actually, you really don't want one if it's not necessary. Not only does the cost to repair go way up, but if you've never been in a car when air bags have deployed, it's quite alarming! Not that the deer impact is not alarming, but without airbag deployment, you can still see, there's no "smoke/dust", nothing is in the way of your hands, and typically, the vehicle is still rather controllable.

Please remember, I speak of likely events, and I'm sure some of you have had cases where the bags did deploy. It's all about the decel/accel rate that is measured by the accelerometers, and they decide if it's a deployable event. No matter, neither event is fun, and both are very costly. The good news is, most people will walk away from events involving deer.
