text: Most of these cars can steer, accelerate, and brake themselves but all cars re-designed to notify the driver when the road ahead requires human skills. For example on paragraph 2 it says "Google cars aren't truly driverless; they still alert the driver to take over when pulling in and out of driveways or dealing with complicated traffic issues, such as navigating through roadwork or accidents." This means the google cars will still have to have human assistance when needed.
