Air Bag Not Deploy problems of the 2012 Volkswagen Golf

I was traveling on a highway in dallas. There was a 2003 Toyota tacoma two lanes to the left of me. He apparently wanted to take an exit that was rapidly coming up. He had a dresser in the bed so he asked his wife if it was clear to cut across all 5 lanes to take the exit. I was two lanes over and rear ended him. He braked when he saw me and I had little time to react, so I hit him front distributed to rear distributed. My air bags did not deploy. I've been a police officer for 17 years and a firefighter even longer and know how air bags work. Since I essentially rear ended him, I know I tripped more than one airbag sensor at a time. My air bags did not deploy. I ended up with a cardiac bruise and upper joint injuries. I called vw customer care and sent them pictures of the car. They think I went under his truck and that's why the bags did not deploy. His truck was stock with no lift kit or anything, so I would hope my bags would deploy, but they didn't. I know we now track if a vehicle's height had been altererd on accident reports in texas. I have a few pictures of the car.
