Just adding my 2 cents. I've started getting this on one small stretch of road - at the exact same place every time - next to my house. I recorded video of it to show I'm not departing the lane. This is definitely a bug with the Emergency Lane Departure Avoidance that was introduced in a recent update. I reported the bug several times but who knows if it'll get fixed soon. Scares the bejeezus out of me and any passengers. No matter what speed I pass this area, it's triggered. I finally turned it off although I wish I didn't have to. But I drive this road every day. It's just past my house.
After viewing the video, does anyone think that the car could be seeing the right side of the road where the city buses can pull out of traffic to stop? Where that section of extra room ends, the curbing makes a 45 degree angle back into traffic to close that section off. Maybe the car sees that as a possible danger?
