There is a distance sensor (think radar or sonar) in the front bumper or grill to measure how far away any vehicle is. The computer can than shut cruise down or apply brakes automatically.
It works in conjunction with a radar system, such as Bendix Wingman, and it adjusts the speed of the cruise control in accordance with the following distances behind vehicles in front of you, so that you maintain a safe following distance.
It's the advanced version of cruise control used to prevent rear end collisions on interstates. Many luxury cars have this which is also known as adaptive cruise control - most all have the stop/go feature too.
If the cruise control on your 1987 300ZX does not work, you might have an issue with the cruise control fuse or wiring. You could also have a problem with the switch that turns the cruise control on and off.
