Hello. New to posting to the forums here but have been lurking for a while. I have a 2017 S 90D running 2017.32.17 software. I was using AP2 on the freeway this past weekend -- 190 miles of uninterrupted, assisted driving! -- when my steering suddenly jerked and shifted my car out of my lane, to the right! Startled me and I grabbed the wheel (breaking off auto steer) and corrected back to my left. Almost ... This is on I94 just east of Hudson WI. There are three lanes heading west, I was in the center lane at the time. A car was shoulder to shoulder with me, on my left (passing lane in the USA). There was some construction happening there with cones on the median, slowly forcing the interior lanes (the passing lanes) to merge to the right. I wasn't paying too close attention but what I think happened was the guy shadowing me got too close and the car jerked right to avoid a collision. I also corrected back into him before I noticed we were almost mirror-to-mirror. There was a car only a few feet behind me in the right-most lane (where the AP intervention put me). I'm sure he was startled too and probably was fuming at me for literally cutting just a few feet in front of him, suddenly. He was not overtaking me, just following at a similar speed to me. All ended up OK but after the adrenaline had been processed and I thought about it, I was left to believe AP2 intervened to avoid a side-to-side impact. Does AP2 include that detection and avoidance logic? (Anyone ...? Anyone ...?) Thank you for any helpful insights.
