ADAS + human driver seems enough to solve most of the shortcomings of both human and robot drivers.
Full self-driving doesn't strike me as necessary to prevent deaths.

There is a moral hazard with ADAS + human drivers:
> Once drivers move from the novelty phase to the post-novelty operational phase, behavioral adaptation may begin to occur and overreliance and over-trust in the automation features potentially develop, including a greater willingness to look away from the forward road (as shown in the VCC data set). [1]
I'm not sure if this is more dangerous than strictly human-operated vehicles, but I would wager that it is more dangerous than strictly autonomous vehicles.

I'm not sure why a semi autonomous system of equivalent driving capability would be more dangerous than strictly autonomous vehicles because of "over-trust" unless one assumes that the driver that overtrust the autonomous vehicles and looks away is also inclined to try to override the semiautonomous system whilst doing so. Humans overtrusting a system capable of imperfect Level 5 driving will certainly not be alert to correct all its errors, but on the other hand they should be capable of correcting more than the baseline (especially if the autonomous system is good enough at general driving under most conditions for the human driver to be restricted to "get me off this road train track or flood the system shouldn't have stopped in" and "follow instructions" type edge cases rather than misidentifying objects at high speed type edge cases.)
If there are additional problems caused by human drivers, it's surely that they are inclined to intentionally override the system with dangerous behaviours which is a separate problem entirely, or that their driving ability has atrophied so much from not driving they are unable to handle the boundaries of Level 4...
Overtrust looks like people sleeping or not even bothering to stay in the front seats of the car. https://www.nbcnews.com/news/us-news/california-highway-patr...
Sure, but I'm failing to see how an autonomous driving system without a steering wheel or brake fitted is safer than one with a steering wheel and brake fitted but the human driver ignoring it and sitting in the back seat.
The actual potential for increased/decreased risk comes when the human driver rightly or wrongly actually intervenes.
You are correct but I think previous comment hung on specific word you used: "semi-autonomous". What that would mean is a system that still requires attention / supervision. What I believe you meant is an AV that still has human controls but is capable of unsupervised driving.
If you aren't familiar with SAE AV levels, check them out. It is a common refrain that L3 AVs are a SUPER bad idea because they would be 99.9% perfect at driving but could still mess up so 'drivers' of them would become too trusting and minimally attentive which would cause accidents.
The common thing is that L3 needs to be skipped entirely so a car should either be L2 and wouldn't be good enough to drive entirely on its own for long periods (lane assist, low speed traffic jam chauffeur, etc) or L4+ where the car can drive on its own but if conditions degrade where it can't continue it is capable of finding a safe spot to stop rather than aborting in the middle of driving suddenly.
The controls vs no controls isn't really an argument. Like you said, it will basically be fine either way if the system is sufficiently advanced especially if autonomy can't be disengaged while moving.
Failing to see or refusing to look is not evidence that something is not there.
The human part is the failure point IMO. The problem is when the human is not in the back seat, but overriding the car.
A car with no wheel, and the human in the back, is not different to one with a wheel and the human in the back, it is when the human is sat in the front only partially controlling the vehicle. That is when it is less safe.
So 2 situations, one where the human can sit anywhere and the car is just as safe, or one where the car is less safe if the human sits in one of the seats.
One of those situations is less safe than the other.
I think the argument for autonomous is that human intervention is, generally, wrongly rather than rightly.
At this point, I won't agree or disagree, but it's getting more interesting all the time.
There was research some years ago in Sweden that cars with 4WD get into accidents 20% - 30% more often than cars with 2WD. And cars with 4WD averaged 10% higher speed at the moment of the crash.
The cause was found to be drivers with 2WD losing a little traction early in their drove and subsequently slowing down, while drivers with 4WD just kept driving like normal until they were suddenly off the road.
Another statistic is that intoxicated or otherwise impaired drivers cause more than half of all fatalities. So making a solution with machine learning and cameras that could retrofit into any existing car and just deny starting the car for such drivers, and having insurance companies cut premiums for having such gadgets installed, would be much more effective than any form of self driving or similar.
https://mb.cision.com/wpyfs/00/00/00/00/00/3E/5A/A2/wkr0011....
The gadgets would have to meet an impossibly low false-positive rate and they'd need to be mandatory and non-removable for this to be effective. Constantly impaired drivers won't voluntarily install the devices, and any non-impaired driver who is falsely prevented from using their car will get rid of the device and not care about the insurance discount.
Also, they really need to be able to detect the other really bad cause of impairment: mobile phone usage.
A tampered car won't pass inspection.
It's like those approval prompts in coding agents. At the start you are reading the commands intently but after being bombarded with them for days you just hit accept on them.
Automatic braking alone is a huge deal: if you're a bit late in braking, you get a warning. If you go past that, brakes auto apply. When configured correctly, I don't even notice it's there 99.9% of the time...and the times I do I'm glad it's there, because the beep pulls you out of a momentary distraction.
The only problem is not every car on the road has it yet.
>Automatic braking alone is a huge deal
Except I had to turn it off for my Ford E-Transit, because it will freak out at nothing. Sometimes it screams at me for cars that aren't even in my lane that suddenly slowed. Sometimes it misjudges a ripple in the crappy asphalt here as an obstacle I'm going to hit. There is a high chance its going to brake for no reason at all and cause an accident.
I left the warning system on, but I will never give it control over the brakes.
Any time I crossed a bridge near me that is kind of steep and has a structure over it, the automatic braking engaged HARD. Like hard enough that I nearly caused accidents until I figured out how to turn it off.
Not great.
Fords seem notorious for this but usually can be fixed. Have you tried driving it to a dealership and trading it in?
Multiple times actually, lmao. Unfortunately its only worth $19,000 currently (sticker price of $67,000 three years ago)
I wonder if there will be some extra liability if the driver kills someone and the logs show automatic braking would have engaged. Something similar happened near me where a lamborghini driver disabled traction control, spun out and killed a girl on the way to school. They had to add new laws increasing the liability if you disabled TC.
Good news, everyone. Soon you won't be able to switch it off.
I suspect this will just lead to people pulling the ABS fuse and losing ABS and ESC along with AEB.
Anecdotally, the only times I've ever noticed these chimes and the auto-braking (even automatic rolling-up of windows), it was false positives, and it was mildly terrifying: for a brief and unexpected moment I was no longer in control of my vehicle. [Recent Honda Civic and Audi A3 models]
I've only had a couple weeks in rentals with automatic emergency braking, and was very nearly been rear-ended twice due to false positives. Anecdotal, and I'm sure they'll improve with time, but I would never allow the system I experienced anywhere near a car I owned. It was profoundly unsafe.
Some years ago, I was in a major crash. The traffic in front of me stopped, I braked hard and stopped in time, the truck behind me rammed me into the car in front. Nearly killed me.
Some time later, I was on a snowy road. The cars in front of me stopped, I stopped, and checked my rearview mirror. There was a truck, who clearly wasn't going to stop. I pulled off to the side, and he hit the car in front of me.
>was very nearly been rear-ended twice due to false positives
To be fair, if the cars behind you had automatic emergency braking you would be at much lower risk of getting rear-ended when there's a false positive.
Pretty much, they would have been getting chimes about being too close to start with.
Assuming you're already stuck with such a vehicle, is there any benefit to a dashcam that captures the alert-noises to prove the that you, the driver, never chose to brake unsafely?
I realize this relies heavily on the questionable sanity and ethics of insurance companies. Even if they agree you aren't personally at fault, they'd probably just increase the premiums for everyone with that model, rather than sue the car manufacturer.
Never hear of someone who was rear ended being liable. Guy behind should keep a distance that allows him reacting in time and he is responsible for keeping that distance.
The same for skiing you don’t have eyes on the back of your head, one behind you is responsible for not crashing into you.
In car you have rear mirrors but if you have something in front of you and breaking you are not going to look in the mirrors.
> The only problem is not every car on the road has it yet.
Yep. ADAS should be mandatory like seat belts and airbags. A regulatory body should be able to come up with a minimum standard for it.
Even airbags were phased in over decades. Front-seat airbags were first available in the early 70s and didn't become mandatory until 20 years later.
Automatic braking can also be hazardous! In a front-wheel drive car, understeer is a fact of life. When you're approaching a bend in the road with your foot in the accelerator, you're going to be pointed at the guardrail, since the car's going to rotate around the bend when lift your foot off the gas. Now imagine you're driving a car with AEB and it slams on the brakes while you were lightly accelerating towards the guardrail, right before you were going to lift your foot off the gas. What was a perfectly routine curve just turned into complete loss of control, and there's a very good chance your car's going straight into the guardrail!
Even when it doesn't slam on the brakes, if you were concentrating on the road, those jarring beeps can just as easily break your focus on driving as they can break your focus on a distraction. I think it's better to avoid distraction by keeping cruise control off, and you can compensate for having human-level reaction time by following at a safe distance and staying in an appropriate gear or setting an appropriate level of regenerative braking to avoid mindlessly getting too close to the car in front of you.
I think that too often, driver assist features are being added to cars to compensate for the other features (like adaptive cruise control) that encourage drivers to mentally disengage from the task of driving. There's also the fact (well, opinion) that driving a car without electronic assists and nannies is fun and engaging (especially on back roads with the windows down and the radio up). Riding in an autonomous vehicle is just as dull as riding on public transportation, all while being less efficient, less social, and worse for the environment.
It would be interesting if we could somehow test how the reduction in crashes with the introduction of driver assists would compare with if we had just banned cruise control, introduced minimum visibility and minimum suspension stiffness standards, and mandated manual transmissions.
This is the perfect expression of chronic windshield brain. If you are driving anywhere near the limits of dynamic stability on a public road, then you are already driving dangerously. Also, computerized stability control works better than 99.99% of human drivers.
The limits of dynamic stability go down drastically when the brakes are locked up. You can be _far_ from the limits of dynamic stability when going around a bend in the road, but if your car locks up the brakes mid-bend, you can unexpectedly go from nowhere close to those limits to exceeding them in the blink of an eye. A human driver would wait until they've straightened out to brake hard, but the computer in a car is entirely at the mercy of whoever programmed it. Hopefully it would do the same, but do you really trust Tesla (or whomever) with their move-fast-and-break-things additude?
Then there's the fact that automatic emergency braking requires the software algorithm to make decisions based on data that is a lot more complex and ambiguous than the data used by electronic stability control and ABS systems. It's much easier to detect steering angle and wheel slippage than it is to detect how an object in the distance is likely to behave.
Confirmed: you don't understand this subject. Any readers who find themselves needing to stop a modern car in an emergency are advised to stand on the brake pedal with maximum force while the computer sorts the situation out.
i don't think you fully understand how many edge cases there really are, and the full range of conditions people here expect autonomous cars or even driver assist systems to function in.
As a very simple example, i sat my driving test in the Netherlands. Literally the first thing my driving instructor taught me was that tires have finite grip and that changing speed or direction requires grip. Doing both at the same time, as you do while driving along a curved highway off ramp can be very dangerous in slippery conditions.
Many, many times, the auto braking and lane centering system in my hyundai car has caused the car to skid in light snow. i have lost count of how many times this has happened. With my previous "non smart" car, this never happened because i know how to drive in the winter.
Respectfully, not all driving conditions and styles are dangerous.
The problem with mostly-but-not-entirely autonomous is that humans will tend to treat it like entirely autonomous.
It doesn't help when manufacturers call their mostly-but-not-entirely autonomous systems Full Self Driving
A manufacturer.
An ADAS would be L4 if it was designed to be truly autonomous. If it's not designed to be truly autonomous, you have to somehow address the attention problem. Even a good attention monitoring system isn't sufficient, because people have the ability to appear superficially attentive by all external metrics, while not engaging with the driving task mentally.
The data to differentiate these levels is pretty limited for a variety of reasons, and the problem only worsens when you conflate AEB with ADAS as the IHS/IEEE do in this article rather than use an OEDR-based definition.
I recently implemented OpenPilot for my vehicle and used it on a 9 hour road trip.
Due to the nuances of my vehicle, the built-in hands-on-wheel nag was still active and required (small) driver wheel inputs every 10 seconds to prevent the beeps. Just keeping both hands on the wheel was enough to pacify the nag. But this forced me to keep attention on the vehicle, more than OpenPilot's face direction detector. Anecdotally I am certain this kept me more engaged than if I could have gone hands off.
The net effect was I had more capacity to be aware of what was going on around me on the road, AND I didn't feel nearly as fatigued at the end of the drive. Keeping the car between the lines consumes a little bit of cognitive energy constantly, which compounds over a long drive. Freeing up that load allowed me to pay more attention to what was happening on the rest of the road. And the mental burden was still half as much--I felt like I had driven maybe 4-5 hours instead of 9.
I have some ideas for how I might disable the built-in nag, but I'm pretty sure doing so would make my car less safe. The current configuration might already achieve the safety maximum for ADAS based on front-facing cameras only.
It increases situational awareness while reducing fatigue, and I think that anything further I try to do will adversely affect one or both of those effects.
