I appreciate your comment and what you're trying to do. I guess I still can't picture how Cruise will achieve the balance between convenience and awareness.
Let's say you're a teenager using Cruise to keep your car within the white lines on a 5-hour, highway road trip. The device is capable of steering the car this way on your behalf.
In that situation, do you stare at the white lines for 5 hours without touching the steering wheel? Or do you text and talk to your friends? What compels you to be just as vigilant about steering and being aware of your surroundings?
I'd say even if you're trying to be a good driver in this situation, your eyes are going to "glaze over" after 1 hour of staring at lines and occasional other cars without using the wheel or pedals. If this is true (and I'll grant it's a fairly big "if"), then this product would effectively impair the driver even more! Are we really that confident that the technology is good enough to lower crash/injury rates, even with zoned-out drivers? Perhaps it's trading one type of crash, for other crashes that are less harmful overall, but do we know?
I'd heard of this kind of fatigue before, and just now pulled up an article abstract[0] in search results. It says "analytical results indicated that 80 min was the safe limit for monotonous highway driving." Highway driving would be even more monotonous with this product. I'l grant that this may not be very solid scientific citation and reasoning here, but it seems like nearly common sense, that a driver can't remain alert for hours on end with a computer doing all his work.
I have a three-hour drive I make twice a week. I can second the motion of "glazed-over" eyes.
But let me tell you: When the "collision avoidance alarm" fired mistakenly once, I was VERY AWAKE for the next half hour.
Assuming the sensors are good, and that they include failsafes that will let you know right away when they AREN'T working, it absolutely would be a net positive to have something else watch during the "boring" times and then let out a loud "Red Alert!" buzz as soon as something unexpected came along.
So no, I don't think the driver would be "impaired even more," at least not if the sensors worked well enough to throw an alarm if something unexpected happened. A set of sensors on top of a car should have a better view of the surroundings than a human, and wouldn't suffer from that kind of fatigue at all.
More, the human is not going to be hypnotized by the road if they aren't actively driving. As a passenger my eyes frequently check out the scenery; as a driver you're forced to watch the road nearly 100% of the time.
P.S. in my drive, I tend to pull over at the halfway point, so after about 90 minutes. And last night that did feel like about 10-15 minutes too long.
What about an AI that asked you questions (especially about your surroundings and the environment ahead of you) and generally engaged you to stay awake?
Even an audio-only version of Duolingo that taught and tested you so you felt productive rather than as though you were wasting time with a prattling AI?
You have to be sure that whatever it is doesn't engage any "spacial" thinking, however. I remember reading about studies that demonstrated that giving people visual descriptions or 3d puzzles was more distracting than other kinds of thinking while driving.
While I sometimes just want to relax, there are times when I'm feeling I COULD be productive if there were something I could do that didn't involve my hands or eyes. :) One thing I've done is to talk into a voice recorder. But there is only so long I can talk about an idea in a useful manner.
Yes, interjecting with questions about the road, traffic in the area, terrain ahead and so on could be helpful if it wasn't too repetitive. I think it would have to be personable and engaging ("Her"-style) to be really effective.

There may be lessons to learn from pilots here. There are countless reports of pilots falling asleep in the cockpit while the autopilot is in control of the plane.
> Highway driving would be even more monotonous with this product
I suspect it would actually be the opposite. If you can take your eyes off the road for say 15-20s every 15 minutes or so, the drive is much less monotonous, and likely safer.
Yeah, others have had some good counterpoints on this too. Maybe another argument with the same point, is that you can't be ready to drive at any moment if you're gawking at the scenery, etc.? (Or is the system actually going to be able to drive certain routes with a "driver" who can allow themselves to not think about driving at all?)
It seems like at some point there would be a qualitative change in the mental processes, where you're effectively not alert to driving, even if you think "I'm only looking away every few minutes." At least if you have been driving for years, where "driving" = "re-evaluating road and vehicle conditions every 3-5 seconds and reacting appropriately." Maybe it should be thought of as learning a new skill, passive driving.
So you'd rather his car automatically keep him in between the lines, so that he feels even more safe and complacent about reading his magazine, and rear-ends you later when you end up in front of him and have to brake suddenly?
I don't think I would. I think that's the point of the naysayers in this sub-thread. Doing X% of driving for bad drivers, might just make them even worse at the remaining (100-X)% of driving.
But the sensors and actuators that are keeping him in his lane would surely fire the brakes far faster and harder than he would while reading his magazine. If all the tech does is keep you in your lane, it's certainly dangerous, but I seriously doubt that's what they are building.

In fact, since human reaction time is on the order of 200ms, the car could likely see what's going on, double-check, and then hit the brakes before he noticed what was going on, even if he were paying rapt attention and expecting you to slam on the brakes.
What is the reaction time of these systems? There are papers on the Internet but they are behind paywalls (that I could probably get through if I were an automotive engineer).
Fair enough; I believe they do include this, or maybe it comes standard with the car. Still, should we be "enabling" bad driving? Are these systems actually capable of letting people safely read while they "drive"? Does a driver have a right to do that? Is it prudent? Who is morally/legally responsible when something goes wrong and damage is done?
I guess as always, we'll figure it out as we go, but I'm not the only one who's a bit nervous.
Playing with phones, shaving, applying makeup, dozing off, etc., are all common. I ride a motorcycle. I'm dreaming of the day when technology makes those thing immaterial to the safety profile of a ton of metal moving at 70mph.
