@bicyclebuck I don't believe it is a bag that is protecting you from the truck. The airbag is to slow down the rate of deceleration the body experiences. An inflated bag didn't prevent the truck from hitting his face.
The front of his truck prevented the other truck from hitting his face. The airbag prevented his face from hitting the hard parts inside his own truck. Without the airbag, the deceleration happens when your face hits hard parts.
I learned this one the hard way when I rear-ended a '55 Chevy Belair. I wasn't wearing a seatbelt and my little Mazda truck didn't have airbags. I was lucky that we were going fairly slow and the guy had already lifted his foot off the brakes when I hit him. My truck's momentum was transferred to his bumper. My momentum was transferred to my truck's steering wheel and dashboard. I learned what it felt like to kiss a steering wheel. I was fortunate that my braces didn't cut completely through my lower lip. It was close. Both of my knees hurt from hitting the lower dashboard. My hands and arms hurt from bracing myself against the steering wheel.
@pip-bip I like it except for the fend flares over the rear wheels. The proportions on those don't look quite right to me. I can see how they were trying to align the tops of the fender flares, but the shape in back doesn't quite work in my opinion.
