I think perhaps this may be different drivers. The scenario I dislike is that drivers seem to fly up behind me, and then brake even heavier, when I’m using engine braking and then tailgate for a period. (For example, I’m going 40 in a 35, and they flew up behind me going 60).

If I tap my brake lights as they’re approaching, they slow more gradually and follow at an appropriate distance.

This is anecdotal of course.

I think the issue is that I’m using engine braking, while those around me are not.
