Thank's for the info!

Today it was raining and I was on the highway traveling ~60mph (car in front was going that fast) with the ACC engaged @70mph. There was a medium amount of road spray from the cars on front of me and I was going to get off at the next exit so I was going to change lanes. I put the turn signal on (the lane keeper system was on too) and started to merge behind another vehicle (light silver in color) that was about a car length away and that car started to slow for the exit. Thinking that the ACC would slow my car down when I got behind this car I was in for a surprise, the ACC acted like there was no car in front of me AND WENT FULL THROTTLE (to get back to 70mph). I quickly pressed on the brake to disengage the ACC but was very startled by the ACC's behavior. Is there anyone out there that has had this issue? Trying to figure out why the ACC did this. Was it the radar, camera, rain, lane change, vehicle distance variation (between the lanes) anybody?
