Roads curving to the right can make oncoming cars (and trees) appear to the cruise to be in front of you, and it reacts accordingly.

For me, braking is more abrupt than I'd like (understandable), but acceleration remains smooth.

Another part of the PCS is the seat belt tensioners. Go to an empty parking lot. Drive at a reasonably low speed (10-15MPH), panic brake, the tensionsers will engage, pulling back into the seat. Without PCS you only have seatbelt locking. It's pretty scary the first time they engage (but cool).
