Tom, I am with you. I got scared when I heard that during the interivew, too.

But I think what he is talking about is a much more complex scenario. Self-driving cars shouldn't freak out at the site of a greyhound bus or a mere cat. But in a much more complex urban setting, you can easily imagine four or five things going on at an intersection. (picture a major intersection in Manhattan)

Rather than waiting for your car to make a decision, you might want to take over the control of your car.

LarryM99, I just laughed out loud about your wife constantly fiddling with the temperature and fan setting of air conditioner. I am with her!

But you do have a point when you said:

The car manufacturers like to think that drivers enjoy the act of driving so much that they would not want to give it up, but I would say that varies significantly from driver to driver and from time to time. 

BMW may be overthinking of their brand -- billed as "sheer pleasure of driving."

Bert, your points are well taken.

But I am not certain if there will be a separate road designated for self-driving cars. Where did you get that info? I would like to check it out. My understanding is that self-driving cars do not necessarily require so-calle infrastructure, although car-to-x infrastructure could presumably provide more intelligence to all drivers.

The first goal should be to make a car that you can drive as you always have.


Yes, I think that's the key. By extention, though, if you are letting your self-driving car drive (but bear in mind that you might need to jump in when the situation gets complex), you don't want the car to override your instinct, either.

With the self-driving car, whether you like it or not, I am guesing that eventually there will a time that your car interferes wtih your own driving. I think this "handover" iussue is a much bigger one than any of us realize today.

BarrySweezey, I agree. That's also my understanding, talking to vendors.

Self-driving cars need not rely on car-to-x infrastructure.  If it's there, it can be useful, but cars can sense their environment and make their decisions on their own.

Good to hear, Bert. But from the story, it sounds like they're still trying to figure that part out.  And I don't want one of those cars on the highway with me until they do.  (I've driven for 4 decades without an accident...knock on wood.)

Uuhh, no, that's the way it works now, Tom. The somnolent or drunk driver, at 3 AM, tooling along at 95 mph, runs into the Greyhound bus because he saw a shadow on the road he throught was a cat.

Self driving cars will eliminate this problem. For one, the car would never let the somnolent or drunk driver to take the controls at all!

Re: Too much technology

Bert: I think you're on the right track. I was a stick-shift driver until once, when buying a new car, I realized the automatic trannies actually got better gas mileage.  When technology becomes better than what we can accomplish on our own, then we hit a tipping point that leads to broad acceptance.

IMHO, we're at least a generation from that tipping point with self-driving cars. But perhaps one day....

Here, you drive!

Fascinating (and scary) stuff!  I was particularly struck by this line:

"There will be times," Santo explained, "when the situation on the road gets too tricky for a driverless car to handle."

So, let me get this straight. I'm in my auto-driven car, tooling down southbound I-5 at 3 am at 95 mph, looking forward to my weekend of debauchery in Tijuana, when my car gets freaked out by something it senses in the road ahead -- maybe a cat, or a Greyhound bus.  So it stirs me from my inattentive haze and says: "Here! You Drive!"  (And then I probably panic, crash and burn.)

Hmmmm. Is that the way it would work?
