Detroit Rock City - Electronic Toll System in the 1970's?
After the boys break "Jem" from the private school and they're driving on the highway, there is a camera shot out the back window of the car. If you look closely, you can see a series of toll/speed trap cameras mounted on an overhead rail. This technolgy wasn't invented or practically used in the 1970's.
