Auto lane change seems to have become much worse for me. The past two days I’ve had multiple hesitations when my 3 was doing an auto lane change. It would start changing lanes and then think there was a car or other obstacle in the way when there wasn’t anything at all and it would ping pong back between the lane I was currently in and the lane I was trying to change to. After the third attempt it made to change lanes I got frustrated and took over control. I’ve never experienced so many issues with auto lane change before. After each incident I submitted a bug report.
You’re not alone. Hope they’ll address this with the next release.
