Most AI projects do not fail because they were wrong. They fail because nobody could explain them.
Researchers at MIT and the self-driving company Motional built a method called CW-Net. It makes a car's decision-making model explain itself in plain words, like approaching stopped vehicle or close to cyclist, at the moment it acts.
Drivers who saw those explanations got better at predicting what the car would do next. The team ran it on a real car on real roads, not only in simulation, and it did not slow the driving down.
The real prize is in the researchers' own framing. Real-time reasoning lets you test a system while it is running, so you find out the model is wrong before it costs you something.
That is the pattern we see over and over. Accuracy is not usually what kills an AI project. Nobody being able to say why it produced what it produced is what kills it.
