Autonomous car

Recent BusinessWeek has an article about autonomous car. Though it is still against the law to have driverless car, but luxury car now offers the option that car can drive for you at speed less than 10 mph or at cruise-control mode at high speed (as long as your hands are still on the wheel). That available package in Mercedes allows you to get off the car at the entrance of parking lot and let the car drive by itself to find the parking space. 10 years from now, for everyone, driving will be much easier and likely much safer.
