Ponch and Jon wait at the Sepulveda Boulevard exit of the San Diego Freeway (I-405) for the suspect driving the stolen car, yet when they give chase on surface streets, they pass a freeway sign for the Foothill Freeway (I-210) east. Soon thereafter, they are chasing the suspect through Chinatown, which is near Downtown Los Angeles (a freeway sign for the 110 is visible in the background), many many miles from anywhere that Sepulveda Boulevard crosses the 405 (either in the San Fernando Valley or in Culver City).
