The car changes 6 times in the last escape sequence.
Twice we see a character hook jumper cables to a car battery and then complete the circuit through the victim. However, the "shock" only comes after he turns the ignition. In fact, the 12-volt shock would occur at the moment the circuit was completed.
The building is clearly a prison yet the group sees a baby crib and a baby incubator.
Heath says about the building on top of the hill that it's a prison and it has a fence around it. Yet no fence is visible from their lower perspective.
The bag on the top of the vehicle changes style and color then disappears and back to a brown bag.
There are very tall hills in the background while the group is driving into the campground and rolling hills as they are driving out at the end. There are no hills like this in Florida.
Although the group is supposed to be in Florida, all license plates displayed are Californian.
