Using the car's on-board internet connection, parking sensors and the in-car entertainment system, the test engineer apparently manages to give the car commands through a remote Twitter connection via his mobile phone. The car then drives forward and lurks about rather abruptly, but the camera then zooms in on the inside of the car which shows no one inside.
The car is then directed to reverse park by the operator using the Twitter account. The CL does actually make the park - presumably using the car's parking sensors and rearview camera - but it comes awfully close to the Mercedes-Benz SLS AMG parked next to it.
The footage is a little bit suspicious with some reports saying it's simply a remote-controlled car. Tell us what you think in the comments section below. It could prove just how far technology can go, but why would anyone want to drive their car through Twitter? Wouldn't it be easier to just get in?
