what always bothers me about the disaster scene

Well I guess mostly how Kim points out "That's the truck that's going to kill everybody!" which is a true statement. However, in her vision, the accident takes place a significant number of minutes after they get on the highway, whereas in real life, it's merely moments after the truck passes. So we're supposed to believe that since Kim didn't get on the highway, the accident happens that much sooner? Implying that her getting on the highway somehow delayed it. Additionally, right after she points out "the truck that's going to kill everybody," it's an entirely different truck that smashes into her friends. I suppose you *could* argue it lost control while trying to steer away from the pile-up, but that still seems iffy to me, because it only leaves a few seconds for the pile-up to occur *and* for that driver to react that way.

I know, it's a horror movie, I'm over-thinking it, but they still always bug me
