Offer a way to navigate to the prior parked location.
Many times I am traveling and stay at a hotel. I then venture out into the local area to eat, events, etc., and wish to return to my hotel. I realize I could have my hotel plugged in the nav, or ask to return to the name of the hotel, and location – however much more convenient to simply say “go to last” and have the car navigate back to where I started my last trip. I can always override it if I don’t like the destination it selected. I would use the words “return to start” but given the go-to” command either “go to start” or “go to last” would suffice.
