I did a search on wipers, AP and found this thread. My wipers turn on early morning (still dark) on single lane county road EVERY time an oncoming vehicle passes. its like the oncoming headlights blind or confuse "vision" it made AP unusable without risking wrecking the wipers being drawn across a clean/dry windsheild.Which.... makes perfect sense if it's a vision only system. Car knows when it needs a wipe to see.
