QQ: Is there any way to prevent TACC/AP from changing the set speed?
I do understand the need to lower a set speed when the car runs into a restricted zone and would not allow Autosteer to continue otherwise, but there is two scenarios that I don't want:
1) When the speed limit drops, but the set speed is still within the parameters for AutoSteer.
2) When the speed limit increases.
Both are majorly annoying. The first one sometimes leads to pretty harsh breaking and is especially problematic when the speed limit in the maps is wrong. The second one even more annoying for me personally though. I tend to stay way below speed limits on most highways (we have by far higher limits than you have in the US...) to both reduce power consumption as well as keep the wind noise level down. And I more than once had the car bump up the speed by 20-30 MPH without prewarning.
