I hate that predictive cruise control so unsafe smh

That +5 and -2 mph parameter, while using predictive cruise control is not true on the new Freightliners.
My cruise will be set to 60mph, then drop to 54mph when approaching a descent, then hold at 65mph well into the descent, then give up the parameter altogether and be at 70mph at the bottom of the hill. It's crap.
Drive your truck...don't let it drive you.
