Someone willing to go to such lengths to abduct her -- in spite of her fighting, in spite of a possible witness in the other car, in spite of her kicking out the window -- that seems like someone who wants HER specifically, and at all costs. He seems to be driven by either obsession or rage, so strong it overrides his fear of being caught. So I can see why her family thinks the kidnapper may be someone she knows (although he could also have been stalking her without her knowing). This doesn't seem like a crime of easy opportunity. But if she WAS a random victim, then he was very brazen, and determined to the point of frenzy. Either way, I really fear for her life.
