Is it really that hard?

Why can't there be a hard coded

  if(big object in front of me) then stop;

??? You don't need AI for that.

What is that big thing that I'm failing to see, that prevents all big auto manufacturers from implementing such a specific and straightforward piece of logic?

In the incident in question, it sounds like the vehicle classified the object as "stationary," before realizing it was a moving person. So the jogger was probably not in the way of the vehicle initially, and by the time it realized it was going to be in its way, it wouldn't have been able to brake in time.

If it had classified the person correctly, it would have been able to anticipate the danger and slowed down / stopped.

That's your speculation,

Also, the human there was able to apply the brakes in time so ...

That's exactly what the article says, not speculation...

The human was able to apply the brakes in time because it recognized the jogger was moving before the vehicle did.

I have a willow tree over my driveway that grows some branches down every year. I don’t always trim them right away because I like the shade. When reversing out, the car often warns about imminent collision; I ignore the warning and let the branches slide over the top of the car. If the car refused then it would be stuck in situations like this.

This sounds dangerous. You’ll eventually get used to the warnings when backing out and wont even check if they’re actually false alarms. Little Timmy becoming pancake mix as a result.

Collision warnings are a backup system. The driver is also expected to look where they're going. Little Timmy will be just fine, unless he made little Sally cry, in which case he's fair game.

I am looking back and using my eyes to make sure the driveway is clear.

and if a neighbor 6 year old daughter decides to retrieve a ball from under your rear wheel you will hear a loud pop

Amazingly I still use these things called rear-view mirrors and backup cameras.

I've wondered the same thing. The only thing I can think of is some kind of god awful false positive rate. Which doesn't really make sense either considering the technology we have today.

Right? To add,

These guys have been doing exactly that for decades, and with very simple sensors and microcontrollers,
