So on my morning commute traveling 70 in a 70 zone, a rock hauler merged on to the highway about a 1/4 mile ahead of me. I was in the left hand lane of 3 with plenty of open space ahead and behind me. The rock hauler traveling about 55 in the 70 zone was littering the expressway with rocks and gravel. One snapped on my windshield, thank goodness for ClearPlex, and I pressed the accelerator to get past this rock dropping paint chipping window breaking hazard. I WAS holding the steering wheel for those that quickly blame that and exceeded the AutoPilot threshold for a couple of seconds at most to get by this menace. Now for the new AutoPilot "Feature". If you exceed the threshold for AutoPilot, even holding the steering wheel, you will be locked out of being able to use AutoPilot for the rest of your drive. I have read about this happening if you are given 3 full on warnings, which I have never even received one of, but not under these circumstances. I will certainly disengage AutoPilot if I have to quickly get by another vehicle in the future but just wanted to share the latest in AutoPilot "enhancements and improvements"
