There’s no word yet whether self-driving cars are actually crashless.

A preliminary study from the University of Michigan Transportation Institute took a look at autonomous vehicle crashes reported by Google, Delphi, and Audi, all of which have licenses to operate self-driving vehicles in a number of states. The researchers, Brandon Schoettle and Michael Sivak, compared that data to adjusted statistics pertaining to conventional vehicles. The study showed that self-driving vehicles were actually involved in more accidents on average, per million miles traveled, than their conventional forebears.
However, the researchers cautioned that those numbers may not tell the whole story. The data was pulled from 11 crashes among three makers of self-driving cars whose fleets only cumulatively drove 1.2 million miles on public roads. The data for conventional cars, however, was derived from a sample of the reported crashes that occurred over 3 trillion miles of annual driving.
