What are my options if I'm about to collide head on with a vehicle with various pieces of lumber strapped to the roof?(Think airbag)

Saturday I was driving along with my s/o in the other seat and a passenger car cut across the inside of a corner, right into my lane. Bad enough, but he also had a few sheets of plywood, some 2X4s, and some 4X4s strapped on top of the car with one of those flimsy tie down straps. I’m thinking get ready to duck because that wood is going to be coming right at our heads. And then I look down and see the airbag. If I duck straight down that thing is going to nail me on the top of the head and most likely break my neck. The shift lever in drive sticks right in the middle of the space between the seats so there really isn’t room for two people to get to the center and still be below the dashboard. I managed to get over enough and he moved a little back into his lane but this has been in my mind since then. Any thoughts?
