I have a new MS 75D with version 2018.10.4. I was driving it today and did not notice any warning when crossing lanes w/o turn signal on. I looked it up later in the manual and it said the steering wheel will vibrate when a wheel crosses a lane w/o turn signal on. It also has to be enabled (mine is). Also, speed must be between 36 and 90 mph(mine was). Can anyone verify that this feature works?
