Maximum Overdrive (1986)

Factual error: The mounted machine gun fires far too many shots for the limited supply of ammo it has in the box attached to it.

News reporter: This frightening mechanical revolt appears to be occurring everywhere. New York, London, New Deli, Moscow, Peking, the reports - or reports we have - are all the same: machines apparently operating by themselves are under the direction of some agency we don't understand are going on a homicidal rampage. Some seem to be waking up more slowly than others. Only one thing is completely certain this morning, and that is: no machine is to be trusted. Unplug all the electrical appliances.

Trivia: The Dixie Boy Truck Stop was built strictly for the movie, and was not a functional stop. However, there were so many real truckers trying to pull in, that the film crew had to put up signs directing them not to stop by. After the filming, people got together and revamped it into a working place and tourist attraction, but closed it after a few months of bad business.

Question: How and why does the glass on the pinball machine shatter all by itself?
