GM drivers demonstrated by positioning a Cadillac at the end of a long straightaway set up in a parking lot. Another car then accelerated toward the rear of the stopped one.

Passengers in the approaching car saw an instrument panel warning appear as the distance to the stopped car shortened. First a green car-shaped emblem was displayed on the in-car screen. Then a yellow, larger version popped up. As the distance closed further, the brake and backup lights of the stopped car began to flash automatically. At the same time, a red warning appeared inside the moving car to signal danger.

At what seemed to be the last moment, automatic braking kicked in and stopped the moving car quickly and safely.
