 In the uncut European version of Death Proof, there is a scene where  Stuntman Mike feels Abernathys feet while she is asleep in the car  and Lee isnt paying attention. When she wakes up from it, he  pretends he just touched them by accident as he was walking by going  to his car. Later when he attacks the girls driving the challenger,  this explains how Abernathy is the only person who recognizes him  from earlier.
