While driving on freeway traffic in front of Clarity began to slow down. In reaction to this brakes were mildly applied, nothing aggressive, and the car was driven towards an open off-ramp to avoid the issue in front. At this moment the car, on its own slammed on the brakes. This created a very unsafe condition and caused following drivers to swerve off the surface of the freeway to avoid a collision with rear end of Clarity. So in short a fairly routing accident avoidance maneuver was turned into a serious and dangerous situation. We are actually concerned this will happen again and lead to an accident. We know the difference between a reasonable application of the brake assist system and what happened here.
