I can't tell if it's just the angle of the video, but it doesn't look like the airbags deployed. Maybe they were intentionally disabled, but yikes, seems like a car you should stay away from until they work the bugs out.
If I understood what I read correctly, the car came out of the gate at 30 MPH. It hit the truck a bit slower than that, it seems. Airbags might be set not to deploy under a certain speed because there might be more risks from the airbags themselves than from the crash below a certain velocity.
Alternatively this may be a prototype with airbags disabled for some reason. Frinstance if you're going to remote-control a car you'd probably wind up fitting something over the steering wheel, so you'd probably disable the airbags for that.
I thought most modern cars had a sensor that detected if someone was sitting in the seat, and only fired the airbag if there was actually a person there. I know my last rental car (I drive an ancient jalopy) had a little 'passenger airbag disabled' icon that went away when a passenger sat in the passenger seat.
