How safe a driver is your average robot? Safer than your average American, at least by one measure.
Google announced Tuesday that its self-driving cars have completed 300,000 miles of test-drives, under a “wide range of conditions,” all without any kind of accident. (The project has seen a few accidents in the past — but only with humans at the wheel.)
To put that into perspective, the average U.S. driver has one accident roughly every 165,000 miles. Here’s how we got that figure: our average mileage per year is 16,550, according to the Federal Highway Administration; the average length of time we go between traffic accidents is 10 years, according to Allstate. (In particularly safe cities such as Fort Collins, Colo., that number can rise to 14 years — which is still no match for Google’s 300,000 miles.)
