Not all auto-braking systems are the same. AAA has reported that there are significant differences between the auto-braking systems made by the car companies. Some of these systems are designed to prevent crashes, while others only try to reduce the severity of the crashes. The crash-prevention systems brake up to twice as fast as the crash-reduction systems. Buyer beware: Like the misnomer "Auto Pilot", "Auto-Braking" systems may not be what their name implies.
