First, glad that everyone is OK.
Sorry to be late to the discussion, but....
I'm retired LEO and have attended more than my share of crashes (after the fact), and I've heard this a lot over the years since the first SRS airbags were installed. People seem disappointed their airgags didn't deploy, but it's understandable. It's a very expensive option that adds to the cost and complexity of vehicles, and is
supposed to act a part in a crash. They are expensive, but like insurance: Only good when you need it, and a waste of money when you don't.
I'd like to dispel some misinformation, and maybe set some folks at ease about this very complicated, but very effective safety system. Please don't take this personal....
Not fast enough to setoff the airbags
Yah, what's up with that? I thought air bags were a lot touchier than that.
I am also surprised the air bags didnt deploy given the front impact.
The criterion for airbag deployment are a lot narrower than most people realize.
I am also surprised the front airbags did not trigger. It does require a certain amount of frontal crushing to do that, so you must have fallen just short of the necessary amount.
It isn't about speed. Simply put, it's the rate of deceleration (distance vs. time), vehicle orientation(s), and direction(s) of inertia (which are often multiple) that engages the system and determines its actions. These can be identical at 20 or 100 MPH. The only difference being the mass's motion interaction with stationary objects, such as pavement and landscape, and changes to the variables during an initial collision, and subsequent collisions (whether hitting, or being hit). A vehicle is not a stationary object. The SRS system is designed to protect occupants. Not vehicles, in any way. The system's purpose is intended to address only one of Newton's laws: the rate of deceleration, as it applies to the occupants. Increasing the time it takes to decelerate reduces the incident of injury to people. We've all heard, "it isn't the fall that kills you, it's the sudden stop". Funny, but it is the truth. A vehicle's braking system does the same thing: a transfer of energy over distance, vs. dumping it all at once. If your brakes caused instant stops, all airbags would be deploying soon after a vehicle leaves the dealer's lot, and a lot more people would be dead or seriously injured. Even a bug on a windshield imparts a level of deceleration upon a vehicle and its occupants. It doesn't end so well for the bug, but that energy went somewhere. It didn't disappear just because you didn't feel it.
If you walk away from a crash and are able to complain that your airbags didn't deploy, you were lucky, and they very likely should not have deployed. An airbag deployment is an extremely violent event, and it's only purpose is to allow an occupant to decelerate slower when impacting vehicle components, such as the steering wheel and dash. If you didn't suffer serious injury (or death) due to an impact (your body vs. a steering wheel, for example), an interaction wasn't necessary. Adding the violent impact of an airbag upon a person adds to the likelihood of greater injury, absent every other incident of impact. I'm sure we've all heard the anecdotes, not unlike the complaint of seatbelts or motorcycle helmets (a discussion for another time), that an airbag deployment "killed" an occupant. I can tell you, that if someone is killed in a collision, and the airbag deployed, the airbag didn't increase the likelihood of injury. Without the airbag deployment, the likelihood is the person would have had greater impact injuries w/o the airbag (more dead, as it were). The programming that controls deployment must weigh the likelihoods of injuries. Of course, there are exceptions. The SRS system is designed by people, and intended to be effective (deploy or not) in every conceivable conglomeration of variables. It's as perfect as any human-designed system can be, or ever has been, prior to any variables of a collision being known. If all crashes were the same, the solution would simple, and no one would ever get hurt. The point being, the use of airbags reduces the depth of injury and likelihood of death in almost every case, including when they don't deploy when they shouldn't. If you're still in the camp that thinks airbags are more dangerous than helpful, please describe for us the details of your next crash, before the crash. Then do the same for the rest of us. That would be more helpful than any safety system.
Anyway, in regards to the OP's crash...
First, the impact of both vehicles. The MOST fortified area of a vehicle (Volt) impacted the LEAST fortified area of a vehicle (Ranger), in regards to occupant protection against injury. This creates the greatest possibility of lesser injury to the Volt occupants, but creates the least possibility of lesser injury to the Ranger occupants, specifically any occupant closest to the points of impact. It appears to me the Volt did it's job to protect the occupants, as did the Ranger, with regard to the specific conditions of that crash. The damage to each vehicle is the energy absorbed by the vehicles and NOT transferred to the occupants. Vehicle damage is energy not spent on people damage. Physical damage helps an investigator determine the course of events of a crash. Monetary damage is of no interest to an investigator outside of statutory limitations. That's for the bean counters and insurance companies. Good luck with that! And remember, if the other driver is determined to be at fault, it is their duty to restore what their actions have cost you. Within legal limits, of course, it is their duty to restore what they took from you, up to and including, repairing or replacing your car, or provide fair compensation. It is not limited to what their insurance wants to cover. It's a civil matter, and their method of replacing your losses should be of no concern to you. If their offer doesn't appeal to you, find another similar car at fair market value, and insist the insurance company purchase it for you (they're called adjusters, but they don't really "adjust" anything but dollar values), or sue the driver for the difference. You may be surprised how often this works. Most people just take the best cash settlement they can, and go away with a loss. Money can purchase transportation, but sitting a Benjamin will take you nowhere.
