I wonder what others here think about what happens when cancelling autopilot while speed restricted on a non-divided highway. Example: I am traveling at 60MPH with autopilot engaged on a 2-lane road. I enter a 40MPH zone as I pass through a small residential area, and the car displays the speed-restricted message as it slows to 45MPH. I turn the wheel to avoid a road surface defect (e.g. pothole) or because Autopilot deals poorly with a sharp curve. The car leaves autopilot but remains in TACC mode, and accelerates to the full 60MPH speed that was set in step 1. I understand why this happens -- because there is no speed restriction for pure TACC, but there is one for autopilot -- but this strikes me as a very, very bad interaction of the speed-restriction and TACC features. The car should, I believe, never accelerate automatically when a driver assistance feature is disengaged. It needs to retain a little more state: when it transitions from a speed-restricted autopilot condition into TACC-only, it needs to reset the TACC speed to the restricted speed. Anything else can cause acceleration that from the driver's point of view is sudden and unexpected -- and that's not good. Do others agree? Note that though one can train oneself to always cancel autopilot with the brake rather than the steering -- and I am a staunch advocate that autopilot-assisted driving is a skill that itself requires the driver to learn and practice a number of new habits for safety, this among them -- it is also possible to cancel autopilot accidentally by bumping or too firmly nudging the wheel. I don't know whether this interaction also happens in the case of the flashing red "TAKE OVER IMMEDIATELY" e.g. when autopilot loses the lane line on a sharp curve. If it does, that'd be particularly bad. There's a section of road near here where the speed limit drops from 55 (straight as an arrow, too) to 30 with a series of very sharp curves where autopilot frequently requires a driver takeover. I never let autopilot enter that area without manually reducing the set speed precisely because I'm worried about this interaction; but I live here, so I know! A driver from another area could be surprised.
