I recently blogged about Google’s efforts to seek suppliers for their new self-driving cars, which you can find here. Six years since beginning to test their self-driving cars, Google happily claims that they are indeed better drivers than your average human motorist. In those six years, Google’s fleet of 20+ self-driving vehicles have had 11 accidents, all of which Google says were caused by nothing more than human error and not the autonomous vehicles.
Chris Urmson, the director of Google’s self-driving car program, calls the 11 accidents minor, involving a few dents and scratches and notes that not once during any of those collisions was a Google car responsible. Instead, many of the accidents were caused by other nearby drivers who have crashed into Google’s cars from behind at traffic lights, side-swiped or hit some of the cars by not following the rules of the road. Most of the accidents occurred on city streets rather than freeways, which should come as a relief and a surprise to people who feared how an autonomous car would perform in fast-moving traffic.
So what makes Google’s autonomous car algorithm a better driver than the rest of us? According to Urmson, it all comes down to how much attention we put on the road versus how much attention a machine puts on the road and everything else around it. Humans are easily and often distracted; Urmson cites statistics that indicate that at any given moment, there are 660,000 people distracted behind the wheel either by checking their devices or other distractions. Currently, Google’s self-driving cars have a safety-driver, a human that is present in case anything does go wrong on the part of the car, and those drivers have witnessed other drivers doing rather strange and very distracting things while on the road. Reading books is a common one, but so is playing a trumpet apparently.
Google’s cars will not be reading books or playing trumpets while rolling down a city street. Instead, the latest sensors on Google’s cars come with 360 degree visibility and 100% attention on the road in all directions at all times. They can also track vehicles, pedestrians and cyclist from a distance of close to two football fields. Looks like they have us humans beat there.
