During a recent What Car? group test, the new Mercedes CLA's Autonomous Emergency Braking (AEB) system behaved unexpectedly and resulted in a collision between it and a Tesla Model 3. In this video, we reveal the full, uncut footage of the crash, explain why the CLA's safety systems triggered a "phantom braking" event, and share the official response from Mercedes regarding the incident. We also discuss a separate incident that occurred on the public road and ask the difficult question: are modern active safety systems causing more problems than they solve?
