I suppose this prevents sudden and perhaps unexpected acceleration to the set speed if A/P is disengaged by jerking the wheel, bit should have been implemented that way, instead of just resetting the speed at limit +5. IMO, requiring more manual inputs is a big step backward in this case.
Or they could have coded it that when going from AP -> TACC, set the speed for TACC to the current speed of travel.I definitely agree that the previous situation needed to be changed...any steering input that cancelled autosteer suddenly rocketed up to the TACC set point! But why not do the obvious thing (joke directed towards head pitchman), and just make the TACC set point also limited to 5mph over when previously in autopilot.
The chosen change is fine for fixing the problem, but now requires the driver to reset the target speed exiting every small town, etc. less "auto"
Basically, what Brunton said:
I can see the potential hazard in the prior implementation. But the fix is really stupid, and is a BIG step backwards in autonomy.
The fix should have been to simply inhibit automatic acceleration of the car without specific manual input ONLY when A/P is disengaged and TACC is not. Instead they chose to inhibit automatic acceleration at all times without specific manual input. Maybe the new functionality was easier to code, but it certainly wasn't the best option.
