PALO ALTO, CA - A self-driving care is officially here and this one isn't just for sale; it's already been sold.
During an overnight, over-the-air software upgrade, Tesla gave its Model S cars autopilot capability. The car uses real-time feedback from front-facing radar, cameras and 360-degree ultrasonic sonar to navigate streets all on its own.
There are a few catches, though. Even though autopilot might suggest you keep your hands to yourself, Tesla says you should rest them on the steering wheel. Also, all the test videos show what it's like to use autopilot in sunny, perfect conditions. But what happens when the weather outside is frightful?
