Sometimes in this magic land of the intarwerbs, fantasy becomes reality. Apparently, this is one of them: A team at the Freie University in Berlin have actually rigged a car so it can be fully controlled with an iPhone.
There are not a lot of details except what you can see in the video. The GPS- and Wi-Fi-equipped Spirit of Berlin—as they called the car—uses drive-by-wire controls, with mechanic parts to operate the pedals. On its top, there are video cameras and pewpewtastic laser 3D sensors.
The iPhone connects to the car using Wi-Fi, transmitting acceleration data to the car in real time. It looks like the real thing, but maybe it's all a four-wheeled Octoberfest joke.
