Morning Driving Thoughts

Do you have reoccurring thoughts while driving? Or play mind games to make the drive more bearable during traffic hours or on empty freeways? I imagine possible collision scenarios. They calm me down when certain things on the road make me nervous. Id est driving between two big rigs. So this morning while a school bus was on my left and a big rig on my right, I thought what would happen if they were to suddenly merge into one another. Would the top portion of my car get sliced off or crushed leaving me underneath one of them? One of my friend was in an accident a few months ago involving a big rig merging into her lane. Her car horn didn't alarm the other driving leaving her to merge right into the space underneath the big rig. All of the her windows shattered, but she came out amazingly undamaged. I can't imagine that my little Ford Focus would protect me as well as her BMW, but I still would like to know what my possible damage would be.
