One thing I did not like was the lane keeping technology. If the car drifts towards the outside of a lane the car is nudged back into the lane, which is fine. However, if you signal a lane change the nannies do not kick in. I did try to change lanes without signaling and the car reacted in a disconcerting manner. I was able to override the lane keeping software, but not before the car strongly tried to keep the car in my lane. In fact, the car actually felt "sloppy" and disconcerting when I forced the lane change without signaling. This could be problematic in a panic lane change situation. My verdict is that it is a great car. And, as long as you always signal a lane change you'll be fine with the lane keeping technology.

You can turn it off, and if you are in emergency you can definitely over power it with 2 hands (I have 2019 540 I don't completely turn it off just make the feedback less)
