I've used mine exactly three times; twice parallel and once, to my surprise, backing into a nose in spot, on a public street, on the side of a slight hill. It took two tries at that, and, because it was a city street, I had to hit the brake when a car was coming around the corner, as I was again edging out into traffic. A "resume" tab popped up, and when the traffic moved on, it resumed.
This week, for the first time, I saw a "P" on the Driver's side. I was in traffic, however, and not quite ready to try parking in oncoming traffic. . .
