Mine was not so great. I tried it this morning for the first time. I put my car in front of a parking space in my parking garage at work. I got out, and followed the instructions (press and hold middle key fob until hazards blink, then press frunk button to tell it to go forward). The car started driving into the spot and then inexplicably turned left, leaving it parked diagonally in two spots. I backed out, straightened the car out, and tried it again. same result. I ended up parking it manually the way I have every other day. The most interesting aspect of the experience is that it is odd to watch your car drive itself with you on the outside and no one inside. They've still got a ways to go on the self-parking thing though. A guy who had just parked his BMW SUV two spots away watched this and commented "Yeah, that could be cool someday if it works."
