After a car chase, a car plows into a truck trailer and a number of drums full of diesel oil.The explosion of the car (which also should not happen because petrol is not explosive) sets off the diesel oil in a large fireball. This should not happen, for the flash point of diesel oil is much higher than the flash point of petrol.
The roll-cage in the van that hooker jumps on the back of, keeps appearing and disappearing during the escape.
When the van with Hooker, Dietrich, and Cowboy rollover, its clearly visible that the gas tank has been removed prior to this stunt.
