In fact if one did a risk analysis of accidents allowing an out of box autoland versus the incident rate of manual approaches that result in screw ups, overruns or land shorts, the reality might be that fully auto land is actually safer straight from the manufacturer!!!
Probably is, if low vis procedures are in force 24/7. Which reduces capacity quite a lot. If protected areas are not protected it might get ugly, just look what singapore did in munich with their 777 during an autoland in CAT I unprotected conditions.
