At about 1:12:30 into the film Rusty Nail pours gasoline over the rear tires of the trailer. However, when he lights it a few seconds later the gasoline fire trail does not go where he poured the gasoline including not lighting the rear tires on fire.
At about the 35 minute mark the 2 cars pull up to a gas station. The 2 girls go in and pay and they leave. No gas is ever pumped.
[10:12]When Rusty Nail uses his PA to talk to the tweekers on the hood, the channel display shows that the CB is on channel 3. When CB's are switched to PA mode the display reads, "PA".
