@Ioniq i know how to get into i-pedal for one pedal driving and how to use the cruise control.
This is a completely different setting, hold right paddle until it says Auto instead of 1,2,3, or i-pedal.
Once in Auto it is my understanding the car should automatically drive at the speed limit without keep reactivating and changing cruise control settings and should brake for cars slowing etc.. you just steer and can also brake with the left paddle if needed.
However when i put it into Auto its just doing nothing
