Despite the name of the video, I'm fairly certain that they weren't even testing self parking. From the articles I have read, it appears they were expecting the vehicle to auto brake to avoid hitting the pedestrian despite the driver having his foot on the accelerator. So the feature that you are able to purchase isn't to stop hitting people when it auto parks, it is for when you are driving slowly in traffic for example not full on accelerating towards an idiot with a camera!
