As Ponch and Jon arrive to the accident scene caused by the two kids in the convertible, you can see the hills in the background are on fire (not part of the show).
From CHiPs Online:
In the first act, Jon is talking with James O'Hara as Baricza shows up in his cruiser. When returning from commercial, we see the same scenes again and Baricza arrives a second time.
The car that O'Hara the midget is driving is a Lincoln. However, when the close-up of him in the car itself shows him speeding down the freeway, the steering wheel and the speedometer/driver dashboard displayed is that of a 1979 Cadillac.
Driving down a narrow alley into a delivery dock, the Preacher covers his eyes after spouting a bible quote. With nowhere to turn and the police hot on their tail, he manages to get totally turned around before being pulled over.
This episode was written by popular novelist Dean Koontz, using the nom de plume of Brian Coffey.
