Does Lane Departure Warning work?

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?

One thing I have to add... I don't know if it works before AP is working. It uses the cameras SO it might not be active until AP is calibrated. Has your AP gone the 30-50 miles and TACC and Autosteer been enabled?

Looking at the manual, it depends on camera calibration, so I would say your cameras aren't calibrated yet!

I agree. I distinctly remember the first time that mine notified me was right after AP woke up. The steering wheel vibration made me think a tire was loose or something, so it was "memorable"

Sorry, I forgot to mention that I have about 175 miles on the car but very few miles using Autopilot. I assumed that the camera calibration is done without the autopilot being engaged.
If the car hasn’t calibrated then autopilot is unavailable. First 50 miles or so in my S75D when I double-pulled to activate autopilot it’d make a noise and flash up autopilot can’t be engages at this time.
The LDW works in mine. First time I thought I had a dodgy tyre. Then I realised what the wobble was.
 
My first P85D model S I could feel AND hear the lane departure warnings, my new P100D I can't hear anything and the "vibration" is so subtle that you hardly notice it and when you do it makes you think you have a suspension or tire problem. Not sure what changed, but the new implementation of the feature is not as good as the older models IMO.

I am glad you and drewg123 mentioned this! I really thought my tire balance was off or something. It is quite subtle, but noticeable. So many things this car does that I have yet to discover.
 
It works. I had one recently when the system got confused on temporary markings due to a construction zone. I actually can share a picture of it but text is in German:

It says:
Take over immediately
Vehicle is leaving lane
