The thing that stands out to me is that the driverless car parked on top of the victim until the fire department arrived and extricated the victim. There are few vehicle-pedestrian crashes where the offending vehicle parked on top of the vehicle and wouldn't be moved; screaming bystanders are usually effective at compelling a driver to roll off the victim.

This isn't a simple matter of "humans good drivers, robots bad drivers"; it's an example of "humans can improvise and respond reasonably to novel situations; robots cannot reliably interpret and respond to novel situations."
