Yesterday I was sitting in my car at the Gilroy Supercharger when I looked over and spotted a red Model S with something strange attached to the side mirror. Upon closer inspection, I found what looks like cameras pointing down at the ground on all four sides of the vehicle. The car had "MFG" manufacturer plates so it's a Tesla car, likely a test car for some future Model S or Model X sensor systems. This could be for an advanced autopilot or a 360 degree camera view like on some other vehicles. Here are the pics is the highest resolution possible. Sorry I didn't get the interior or the complete VIN or get to talk to the driver. I have no other pictures.
