Don't disable AP on lane change

Problem: Driving with AP. Press on turn signal - AP turns off. Needs to be restarted manually upon completed lane change.

Solution: While the car is on turn signal (changing lane), revert back to TACC, but when turn signal stops, get back to AP automatically. Only change is needed that AP would "nap" while turn signal is on.

That doesn't sound right. With AP on, the signal should change lanes without disengaging.

You're saying it does this universally, even on highways?

It may be limited on some secondary roads; the lane change on secondary roads was a feature they added well after AP debuted and some secondary roads seem to have stricter speed restrictions than others. Maybe lane changing too?
