Second straight episode where a vehicle is referred to as a "beast."
Dragnet 1967 (1967) fans will recognize the character name Steve Deal. That name was used in The Big Ad (1967). Deal was played by Don Dubbins, a frequent actor on the series, he who also appears in Suspended (1973) later this season of this series.
This story was likely based on the "onion field" kidnapping of two LAPD officers in March of 1963 by two criminals that the officers had pulled over for a routine traffic stop (subsequently depicted in The Onion Field (1979)). In that situation, one of the officers was killed, and the other seriously emotionally damaged for the rest of his life after narrowly escaping from the men.
