Perfection eludes the machine. Google's fleet of nearly five dozen self-driving cars has passed the 2 million miles on the road mark, putting the likes of Uber, which has autonomous taxis operating in Pittsburgh, Pennsylvania, in the shade. Google first began dabbling with self-driving science in 2009, and lead engineer Dmitri Dolgov said the first 90% of the work is easy, but the last 10% is hard as it "requires teaching the car to handle edge cases". Google's self-driving car has required human intervention 341 times over 423,000 miles. The company says that its vehicles have driven more than 1 billion miles, a figure that's likely inflated by the fact that some are still being tested.
