I also once opened the door after waiting about five minutes after getting the “driver is approaching” notification to hear two people bitching about “how ridiculous” it was finding my place. They were in my driveway but could not find the front door. My house is on a hill so the door is down a flight of stairs from the garage but it’s only about 20 feet away and plainly visible from the street.
The building itself looks like a garage from the road, so many pass by the unmarked door they need to enter the code on. Also, there's three consecutive lanes you can turn right onto, so when Waze tells them to turn right, only 33% of drivers get it correct else they get lost in a maze of parking lots and dead ends. This is also after the driver successfully navigates a roundabout (hard for some US drivers) and does not accidentally getting back onto the interstate because the lanes are not clearly marked.
