While self-driving cars haven’t yet been deployed on a large scale, they already appear to be statistically safer than human drivers. For reference, in the United States there were around 5.4 million crashes in 2010, resulting in 32,999 deaths (which is around the average number of deaths per year since 2008). Meanwhile, according to a study from Virginia Tech Transportation Institute—which was commissioned by Google—self-driving cars had 3.2 accidents per million miles, compared to 4.2 accidents per million miles for humans. The study also believed, but couldn’t prove that the self-driving car accidents weren’t as severe.Of course, it’s still too early to say that driverless cars would definitely be safer in mass use. The closest we have right now are Tesla vehicles that aren’t fully autonomous, and the federal government is only putting forward its first set of regulations regarding driverless cars tomorrow. However, self-driving cars still have some obvious advantages. They don’t drive drunk, they don’t get road rage, and they adhere more closely to the rules of the road than we feel comfortable doing. Even if they’re not ready to hit the road, they can teach us a few things about being safe.
