Had just merged onto the beltline highway and engaged EAP at a follow distance of 4. Due to the terrain (hill crest) and the size of the car in front of me I couldn't see the traffic further up the road. Suddenly EAP starts aggressively braking. Not quite emergency, but hard. In a fraction of a second I'm thinking, "WTF no brake lights on the car in front - Y U DO DIS??!" Well it had seen two cars ahead and realized the speed delta was great. The driver in front of me violently swerved into the adjacent lane - luckily unoccupied. Of course my car slows down appropriately, handling everything like a champ. Had I been driving my old 2009 BMW X3 it may have been a different story. You always hear these stories about AP doing things badly. Well, it also does things correctly more often than not. Just thought I'd share.
