The problem is not... generally.. the truckers. I was riding shotgun with my brother and he ask where a motorcycle that suddenly appeared in front of us was.
(He had come up on the right. there is a reason you should not pass on the right except at an intersection where the car you are passing is turning LEFT)
I said "I don't know but I think we have tire tracks on our front bumper" Meaning he road over it. or at least close enough to touch it.
Cutting in front of a Semi like that is ... Or any other vehicle for that matter... IS simply stupid. and I've had it happen with my motor home (And one of those little rag top sports car would not have even made a good bump if I'd have run over it) and in my car. DO NOT cut in front of people if you enjoy life... IF you want to die, there are better ways.
