Front Air Bag Sensor Control problems of the 1999 Dodge Dakota

I was involved in a three vehicle collision with myself being in the middle of two other pickup trucks. The truck in front of me had a trailer hitch on the back causing all of the impact to be in the middle of my front end resulting in a u-shaped indentation going back into the engine of my truck. The collision was on an interstate and we were moving at approx. 50mph slowing due to the vehicle in front stopping suddenly. I struck the vehicle in front, bounced backward, then was struck in the rear very hard pushing me back into the front vehicle. Neither the drivers or passengers airbags in my vehicle deployed. Later speaking with the accident appraiser he stated that the airbag sensors are located on the left and right side of the front bumper and not in the middle. By the impact being in the middle of my front end the sensors were not triggered because the sensors never knew there was a collision. I believe this is a serious defect that should be investigated, there were injuries from moving forward, thankfully no one was very seriously injured but it could have been worse. Shouldn't there be sensors in the middle of the front ends also just for this type collision, I. E. All of the impact being in the center of the front end. Thank you.
