Isn't this mixing two different things? The average driver "has" one accident per 165,000 miles, driverless cars haven't "caused" an accident. The current article discusses accidents not included in this Mashable calculation. Even if driverless cars don't "cause" accidents, they may be involved in more accidents per mile (I don't think we know yet publicly). It may be the case that human drivers are better at avoiding unexpected dangerous situations, for example.
