Well, mine does. Similar reports from others with luxury or trophys...
I would not know how much one bar actually is. I can imagine this is referenced to the car ahead of you. So, regardless your own speed if the car in front of you is doing 85kmh, one second distance would cause my car to reduce speed at around 23-24 meters distance. If the car in front is doing 100kmh, the distance will be around 27-28 meters.
I do not recall this to happen. What I do see is the speed drop is excessive, and more drastic with high regen active.
