On one hand I understand that it is a monumental advance in technology.

On the other hand a computer can recognize a unique face from pretty far.

A computer can recognize a face assuming it has a clear view of the face and has the time to process it. But that’s really not the problem.

If you are in your self driving car and it sees a blob on the road, what is that blob?

A piece of cardboard that’s blown onto the road? An animal that’s wandered onto the road?
Is it a rock that’s fallen off a truck?
Did a person slip trying to cross the road?
Did something fall off someone’s car?

What do you do when it’s raining/snowing so hard you can’t see 3ft in front of you?

What happens if the sensors are dirty and not able to get a reading clearly?

What if the road is incredibly worn that it’s nearly impossible to see the lines?

What if the roads are covered with an inch of snow?

You are in a moving vehicle, it only has fractions of a second to see, recognize and react. Being able to accurately recognize hazards is incredibly difficult because a false reading could be incredibly dangerous to the driver or anyone in the area.
