Actually, this happend to me on PA turnpike where HA thinks that I am driving on 3 lanes when it was actually a 2 lanes. It even picked up the car driving opposite direction and disengaged HA because it think it was going to crash into me (the other vehicle was driving very close to shoulder
It was only the center tube- went through midtown and Lincoln both ways and only had that issue on the center. The center tube changes direction depending on time of day and it's two way on weekends.
