I've seen (in other places) comments that the Trucker should have done something.
What.. I mean who'd a thunk the idiot in the RV would change lanes too soon.
And short of spiking the brakes what could the Trucker have done? (And spiking the brakes on a semi is not all that recommended)
Sure he could have backed off the accelerator (and likely did) but the idiot in the RV was too fast for him to avoid.
What the Semi driver DID do was maintain control of his vehicle.. Though the relative size helps him.. I suspect he was still in need of a change of underwear. I know I would have been.
