In this episode, Connie Cezon (as "Gertie") has her longest on-screen appearance in this entire series here, owing to the absence of Della Street (Barbara Hale) from the episode.
In this episode, the end title credit "Automobiles Supplied by Ford Motor Company" specifically refers to both Perry's white 1964 Lincoln Continental sedan and the 1950 Ford Woody Estate Wagon that's used in the hit-and-run murder central to the plot.
When the true murderer confesses, he or she says the line "And I would have gotten away with it, too if it wasn't for your meddling..." There's a possibility that the production team for Scooby Doo, Where Are You! (1969) may have lifted that line from this episode and used it as the confession line for most "ghosts" whenever their identity was revealed. The end of that line, of course, was changed to "... you meddling kids" (sometimes they also include "and that dog.").
In real life, hitting the victim with a car is a common means of committing murder, but this is the only instance of a murder victim being hit with a car in this series. There are instances in the series of accidental victim hit with a car, fake murders with dummies being hit with cars, and already dead murder victims being hit with cars to confuse the police.
