Had there not been pilots in the 767's back on September 11, 2001, the World Trade Center towers would still be standing. Those planes were designed and tested as well as all modern Boeing and Airbus planes to takeofff, fly and land automated since the early 1990's.
As many of the people who have posted here have stated, computer systems can pay attention to all directions 100% of the time. You use the distracted child, running out in front of the car. A good example, is a small child between two parked cars, hidden from the driver's view. In one demo I saw of automated driver technology, there were motion camera systems mounted below the front bumper of the car. It could detect the motion of the child's legs moving toward the street and apply the brakes and sound the horn, long before the child was ever viewable by the driver. This also assumes you were looking at the car and not the mirror at that split second.
Many people here have mentioned about system failures and cars crashing. The systems are built with redundancy, and if failures begins to occur, the system shuts down in a controlled manner, similar to how the limp mode works on the auto computers today.
Because of all of the sensor technology required for these systems to operate properly, these cars typically will not function correctly if they are not in perfect working order. In wet weather, if sensors detect too much wheel slippage, they will expect the tires to be replaced. If sensors pickup too much vibration because of a bad bearing or joint, again, the system will probably demand repair. The end result will be safer cars on the road.
