* Collision avoidance systems are terrible at forecasting collisions because they almost never result in a collision. (The point of the system is to help you avoid an upcoming collision.)
* The prediction that Y2K would happen was a bad one since it didn't happen. (We spent billions of dollars to make sure it didn't.)
* The 1978 prediction that the ozone layer would be depleted by 2010 was a bad one since it didn't happen. (Humans took action to reverse CFCs and the ozone layer began to regenerate.)
