Wind Chill (2007) on Netflix

Plot summary

At a Pennsylvania university, a student known only as Girl finds a ride to go home to Wilmington, Delaware for Christmas on the campus rideshare board. The driver, Guy, shares one of her classes, went unnoticed by her, and appears to know more about her than a stranger would. At an isolated gas station the restroom door jams, and from inside Girl hears Guy and the clerk talking as though they cannot hear her pound on it. Guy then leaves the highway for a road marked with accident crosses, calling it a scenic shortcut. Girl works out that he lied about living in Delaware, and a car races straight at them; Guy swerves and they crash into a snowdrift while the other car vanishes without tire tracks.
