Autopilot is generally only operated in fair-weather and good visibility. Sensible drivers, under other conditions, would not handover responsibility to the machine. In other words, the driver chooses to give the cars the 'cakewalk'. In addition, the Autopilot has a redundant backup -- namely the human operator. There could be thousands of unreported crashes/deaths but for the intervention of the human operator. Accordingly, dividing 9 by 'billions and billions' is not directly attributable to the skills of the Autopilot.
