Side/window Air Bag problems of the 2016 Tesla Model S

My Tesla p90d 2016 was hit by a sprinkler truck on driver side,luckily ,I was fine and I am pretty sure the door was very firm. However, the side air bag didn't work and the door's shape had obvious change and tightly against me. I will attach photos below. I concern the sensor' position is too low or the quantity's too less. When accident happened, both of vehicle in motion on a crossroad. The sprinkler truck was full loaded.
