As long as they're not cutting out moments before a crash to shift liability at the last second I don't see the problem. Disabling the system early when it's not sure it can operate safely is way better than not doing that and plowing into the side of a truck because the driver enabled it on a road with un-signaled cross traffic. (When the car could know from map data it's on a road it's not well equipped to handle mind you)
