Well... Watson's cognitive computing model doesn't really map well to the autonomous navigation problem when unexpected events occur.

Do I continue on this road until I reach the flaming fuel truck I can see up ahead? Do I sit here in the path of the boulder rolling down the hill? Or do I just say "to heck with it," this route looks too dangerous? A human would high-tail it out of there. The computer would travel until it decided it was too close to the heat source or it was impacted by the boulder.

The human brain has had thousands of years to become adept at navigating obstacles.

Watch the tape sometime. To be fair, part of the win was reaction time. The time it takes a human to lift his arm and hit a buzzer is much longer than the instantaneous speed of a machine accessing a database.

I doubt they can program a car to handle the subtle maneuvering that happens on the road all the time.

Have they done any tests (in a closed area) where they send "jerk" drivers at the car?

It had to physically push the same button just like the human players, whether it was calibrated to account for human muscle I don't know. It just illustrates the advantages a computer has, I don't think anyone is going to be concerned if a computer has an unfair advantage driving a car.

Not so smart?? Techy stuff are great when they work, but what a nightmare they are when they do not work and have a cascading effect knocking other things out, the nightmare is just not worth it.

LESS is MORE.

I want a car that has ticker signs I can activate like: YOU ARE IN THE PASSING LANE! PASS AND GET THE HELL OUT OF THE WAY....

Cops are going to give tickets for that and it is about time. When they tie up the lane and people start going around them. THAT IS DANGEROUS.

How many hundreds of thousand of years has it taken for mankind to reach the physical and mental state it's in now?
And you are 100% wrong. Self-driving cars have driven hundreds of thousands of miles without having accidents attributed to them.

Humans have the ability to recognize potential hazards and compensate for them. Computers are reactionary and respond to imminent hazards.

A human can drive along a road, see a boulder rolling down the hill up ahead, and stop before reaching that point.
A computer will drive along a road, receive an impact from a boulder, and try to recover.

And you don't think computers in cars will be developed for... driving?

As for humans having the ability to recognize potential hazards and compensate for them... computers can as well. In your example, not only could a computer detect the boulder, it could detect it and brake (or turn or otherwise avoid the danger) much quicker than a human. Reaction time for humans can be in the hundreds of milliseconds. For computers you are talking about way, way, way less than 1 millisecond. And they are only getting faster.

I don't dispute the fact that a computer can outperform a human when it comes to computations...

But you have clearly and unwittingly showed showed us why autonomous vehicles are still decades away. I bolded your statement. In many situations driving is NOT clearly defined...

As far as mentally driving is not a very complicated task, it's just reason and if we can produce a computer with enough reason to dominate on Jeopardy driving a car is no brainer... pun intended. A computer is never going to have the flaws of a human such as their mind wandering instead of concentrating on the task at hand.
And a computer (at least for quite a few decades) will not match the human brain for unseen issues...

As long as it's on a racetrack or somewhere where it's rules and the road it travels is <ahem> clearly defined I agree...

I'll relax more once it's shown that an autonomous car can navigate through Los Angeles traffic through the mountains to Las Vegas and drive on streets where children are playing or where bicyclists are riding...
