The Police should ask for the raw footage and at any rate the AD will if there's any doubt. They will probably engage a forensic computer tech expert as well and possibly ASU professors/engineers. But from a black box perspective it's clear that the system didn't not detect anything. Still IANAL but I would probably guess there will be a reckless driving charge for the driver here.. mitigated by the pedestrian failing to yield to the car by not crossing at a cross walk. The human driver was clearly not paying attention and there is video evidence of that. If the driver had kept their eyes on the road and the accident had still happened then it probably would be no charges filed.
