The killer / kzl-303 (uncredited)

Based on an urban legend where a woman stops at a bathroom and is held hostage and it turns out she imagined the whole thing

As the two cars drive down the highway after leaving the motel you can see the crew/other cars reflected in the side of them as they drive past.

In Nicole and Jess's love scene, while she's filming him, you can see he's got a patch of hair in the middle of his chest, but in all of the close-up shots of their chests, the guy's chest is completely shaved.

After Nicole and Jess drive away from the house at the beginning of the picture and are shown driving on the highway, they pass under a sign that says "Soledad Highway exit", which means that they're driving on the Antelope Valley Freeway (CA State Rt. 14), north of Los Angeles. But shortly afterwards they pass another sign on the side of the road that says "Welcome to California", implying that they've just crossed the border into California, when in reality at that point they would have already been in California for quite some time.
