I have it set to be aggressive when braking on the highway and less aggressive in the city, but was not moved while travelling and is where I set it when I left that morning.
It would just start braking on its own. First it would be barely noticeable, then actually slow the rig down for a couple of seconds. Then it would let up for several minutes before doing it again.
