I keep trying to think of a scenario where I would want to park my car while standing next to it. I guess an automatic parking app could come in handy for tight fits that offer little door room. 9to5Mac discovered a video of auto-parts supplier Valeo parking a car using nothing but an iPhone.
At the end of the video, a Valeo representative stands outside a Volkswagen Sharan and parks it using an iPhone (:55 mark). The Automatic Park4U system doesn't control steering, that's left to several sensors that can parallel park with just 22 inches of clearance.
