Crash rates for self-driving cars are lower than the national crash rate of conventional cars, according to a new report out of Virginia Tech Transportation Institute that was commissioned by self-driving car developer Google.
While self-driving cars have a rate of 3.2 crashes per million of miles, traditional driver-operated cars have a rate of 4.2 crashes per million miles, according to the study that adjusted the data for unreported crashes and takes into account accident severity.
The authors note that the data also suggest that conventional vehicles may have higher rates of more severe crashes than self-driving cars, but there is insufficient data to draw this conclusion with strong confidence given the small overall number of crashes for the self-driving cars.
