Google's self-driving cars are getting smarter. After logging nearly 700,000 miles without a driver, the autonomous cars are capable of reacting to a multitude of scenarios unique to city driving. The company released a video
which shows one of the cars driving through Mountain View, California, home of Google's global headquarters. The autonomous car was able to safely navigate a parked car protruding into its lane, avoid a biker weaving in and out of the bike lane, and approach railroad crossings with prudent caution.
