I have the Tucson Hybrid Limited version in the US and I did not see that Walk-away Lock feature. There is a feature that can be set to Lock upon moving the gear selector from Park to any drive mode. Theoretically, the Walk-away feature could be added as a software update, but I wouldn't count on it since it wouldn't then match their already printed owners manual. Hopefully, Hyundai & other mfgrs catch up to Tesla with the ability to add features on the fly without boxing themselves in with a printed user manual.
