Yes, and how many more miles are driven by human drivers in the US compared to autonomous vehicles? Obviously there is going to be a disparity in the number of deaths. What is important is the number of deaths per mile. Further complicating matters is the fact that most of the miles being driven by these autonomous vehicles are being done with human operators trained to be alert and the unique quirks of an autonomous vehicle. They will likely be much prepared to stop an accident from occurring when the car makes a mistake than an average consumer. Autonomous driving may in fact be revolutionary and reduce the number of traffic deaths dramatically, but it is still early enough in development that there isn't any evidence to bank on anything at this point. There certainly isn't enough to rush the tech out the door either on the public either.
