When Nan tries to run over the hitchhiker, she swerves her car, a light-colored 1959 Mercury, at him. But in the insert shot that shows the car swerving, it's a black 1957 Ford.
The sequence shown was lifted from Perry Mason S1 E1 "The Restless Redhead" which includes a car chase with a black '57 Ford sedan. Both shows were originally on CBS.

When Nan's car runs out of gas in New Mexico she walks down a road and passes a sign reading "Gas Eats Just Ahead". The sign is facing the same direction she is walking, indicating that "just ahead" is the other way. Yet she continues walking in the same direction away from it.
Nan's car, a 1959 Mercury, has had its vent windows removed (and the side windows are always open). This was obviously done so they would not block the camera angles of Inger Stevens.
The woman mentions that she's taking "Route 80" multiple times. She also mentions that she's driving through Virginia, Tennessee, Arkansas, and New Mexico, neither I-80 nor U.S. Route 80 run through any of these states.
When Nan, in her car, escapes the oncoming train, the locomotive is clearly marked "SP" on the nose. The Southern Pacific RR did not serve the part of the US she was supposed to be in. It is obviously footage shot in California, where the SP did run.
The opening narration states that Nan is getting her tire changed in Pennsylvania. Later, Nan states that she sees the hitch-hiker in Virginia 50 miles after she has seen him for the second time. She would not be going through Virginia AFTER passing through Pennsylvania when driving west from New York to California.
When Nan opens her valet in the gas station and sees the hitch-hiker in the mirror, the station's address (5075 Cornell Road, Agoura Calif) is clearly visible on the window where the fan belts are hanging. She was supposed to be in Pennsylvania at the time.
When the sailor meets Nan at the closed service station, he asks about her car then tells her she left her keys in it. Yet he fails to mention she left her lights on (which would drain the battery) nor did he turn them off when he noticed her keys, as they are still on when they return to the car with a can of gas.
