Pamela begins writing "TOMORROW'S BACON" on the door of the truck in close-up, the camera then cuts to a longer distance shot of her completing the word "bacon" but the way the letters are styled do not match the close-up.
(at around 15 mins) After Quid's truck and the green van pass the man hauling a sailboat, the man's windshield suddenly breaks for no reason; it looks like a strange jump cut with a few seconds missing. In the next frontal shot of the car, the windshield is broken but still in one piece despite the previous shot showing some of it falling apart.
The speedometer in Quid's truck is calibrated in miles per hour. All vehicles sold in Australia after 1972 had speedometers calibrated in kilometers per hour. This truck is a 1976 model.
When stopped in Western Australia by the Police, Quid is asked for his driver's log book. In 1981 both interstate and local truck drivers were not required to maintain a log book in Western Australia. Consequently, if you were stopped by the Police they would never ask to see your log book.
Quid is towing a "freezer" trailer with a Thermo King refrigeration unit (the "TK" logo can be seen on the trailer in several scenes). These refrigeration units are powered by a separate (and very noisy) engine attached to the trailer the size of a small car engine and they operate basically 24/7 to keep the contents of the trailer close to freezing point. Not once in all the scenes Quid's truck is parked do you hear the refrigeration operating.
When Quid and Hitch are discussing the man in the green van driving down the road the clouds outside the window don't pass across the view.
Quid leaves Melbourne, Victoria one morning and on the same day, after all his mis-adventures, stops at Yellowdine Roadhouse in Western Australia to call the police. This is impossible because Melbourne to Yellowdine is about 3100km or about 1900 miles. Without stopping it takes about 32 hours to drive a truck between these two locations.
Toward the end of the movie, as Quid approaches Perth, in Western Australia, he passes a sign that reads "Perth 40". Being 1981 this would mean he was 40 kilometers from the center of Perth. Even in 1981 40km from Perth City was well and truly a built up area with street lights and houses along Great Eastern Hwy yet Quid is clearly still driving in the 'bush'.
The police car that pulls Quid over after he has traveled past Yellowdine has Victorian number plates. There would be no Victorian police patrolling a road 3000km from their home base.
The sign announcing the Eastern side of the Nullarbor Plain is misspelled "Nullabor".
Quid says dingoes don't bark which is not true. (As it turns out, his dog, Bosworth, isn't a dingo, so he's even wrong about that.)
Quid is seen looking into the van's front seat to see the cooler, but he sits to the right in the cab, but the van is seen passing to the left.
At the beginning when Keach passes the car towing the boat, he says "I'm on your port side." The nautical term port refers to the left side, but since drivers drive on the left side of the road in Australia he is actually on the starboard, or right, side. (He tells the driver to pull over to his port side so he can pass to his right or starboard side.)
