I reported this to Tesla Support today. Spent almost an hour with them on the phone. I dowloaded 2019.16.2 last night. The car panicked several times on my way to work this morning. A couple were downright scary. All of them, in my opinion, were false positives, but the most distressing thing is that I have no way to disable this feature. Yes, you can scroll through the menu and disable every time you put the car in drive, but it resets itself back to 'enabled' every time you put the car in park. I'm begging them to find some internal control that tech support can set in my car to permanently deactivate Emergency Lane Assist.
To clarify, this is not the "Lane Assist" feature, I have that turned off. This is clearly the Emergency Lane Assist. I was not using any auto steer or cruise control at the time.
1st time: driving on a narrow two way country road at 45mph. I passed some trash bins near the curb on my passenger side. My Model 3 panicked as if the bins were a car, and yanked the wheel to the left, and I slightly crossed over the center line (INTO ONCOMING TRAFFIC) (Fortunately the oncoming car was quite a ways back). This was a very unnerving feeling, that my car is going to jump at its own shadow. I immediately remembered the software update, pulled over, and disabled the feature.
2nd time: Driving through a parking lot (well under 45mph), I crossed over some white lines towards the end of a parking row. The car thought I was departing some sort of lane and yanked the wheel left and right, causing my trajectory to move left and right about half a foot in either direction. Mostly I was surprised because I didn't yet realize this feature re-enables itself (which it tells you in a notification message when you turn it off). If I had been cutting close to a parking block, I might have run over it.
3rd time: Narrow country road, two-way traffic. An oncoming car caused my car to panic and yanked the wheel to the right. Again, not the direction I want to go (with there being a steep ravine about 12" beyond the white line to the right). Not a good feeling.
