Do you feel safer with self-driving cars on the road?

[Greg Bernhardt]

Yeh, I know, a lot of people just amazed by new technology, I am just not one of those.

Do you not fly on airplanes that use auto pilot?

All I know is people died already because of the self driving car failed, I think it's a Tesla. It was on the news.

Maybe you missed this? NTSB says Tesla not at fault.
https://www.wired.com/2017/01/probing-teslas-deadly-crash-feds-say-yay-self-driving/

say they never fail is very idealistic. They fail.

What is important is the probability of a human failing vs computer. My bet is humans will fail far more often.

 

[Stavros Kiri]

BTW, it is not a fair comparison between auto pilot in planes and cars. There are so so fewer planes than cars.

More cars, more accidents. Less planes but a lot less accidents. Statistically planes are safer, especially auto pilots.
(All these as far as I know so far)

Planes has a wide open space and FAA has regulation planes cannot get within a certain distant ( big distance) between planes. Try having plane traffic jam like cars. This is like if you have auto drive cars in a desert or in Alaska, you are the only one on the road, then it is safe. Try bumper to bumper, with lousy drivers.

There may be a point here, I am not sure, but 1) we have to compare something with something 2) failure is failure ...

Yeh, I know, a lot of people just amazed by new technology, I am just not one of those.

I am not naively amazed either. I know what you mean. I am a simple person, as well as complicated, and I like simple life almost as well as (or a bit more than) modern technology, but in any case I think the latter is necessary, because now humans and technology/machines evolve together, otherwise there would be a major set-back.

You like to take the chance, by all means.

No chances ... no progress! ...

Number of planes vs accident is not linear. You can have malfunction, but if you have more time to react, you can avoid accident. In heavy traffic, you have split second to react, any malfunction is deadly.

One more important difference, airline pilots are well trained, two people one check the other. Car drivers are morons, you have drunk drivers, you can't compare.

 

[Greg Bernhardt]

Car drivers are morons, you have drunk drivers, you can't compare.

Isn't that an argument to put control of cars into computer's hands?

 

[yungman]

No, I mean can the auto pilot react to it.

 

[Greg Bernhardt]

React to the drunk driver? Shouldn't the drunk be asleep in the back seat of their car while the car safely drives him/her home? Are you saying you can react to a drunk faster than a computer?

 

[yungman]

Don't forget about the hacking. Before you know it, they will have Netflix for passenger, you have apps to find things, to do things, all sort of fancy things that go right back to a full blown computer communicating with the rest of the world, there you go hacking.

No, moron want to drive wild. I was young once, I did went out intentionally driving drunk! Yes, I was stupid, but I am sure I am not the only one.

I think he means one sdc versus drunks

Right, are you saying you as a human will be able to react faster/safer to a drunk than your car computer?

 

[yungman]

Guys, I don't want to get into debate. Ha ha, I am 64, I doubt I will see the day cars all driving on their own. To each their own, this is a never ending debate. I designed so much electronics, I become pessimistic. My engineer can't even write the AHDL right and I had to go in and deglitch the FPGA!

I better get out of this.

 

[Stavros Kiri]

It's a discussion. No one is attacking anyone. Both sides said good points. But as you wish.

 

[jack action]

I absolutely do not feel safe with autonomous cars. 40 years after PC becomes popular, you still have blue screen, freezing and all. When I PC froze, you swear, you kick and you restart it. When you are in on the road and the car goes crazy, you can get killed.

@yungman , I thought of you today. While watching a show, my TV went mute out of the blue. Start zapping, it's on all channels. Long story short, I unplug the cable terminal for a few minutes, re-plug it and wait for the reset. The sound is back on.

I'm wondering if a self-driven vehicle will need a reset like that from time to time? You know, after you loose the steering or the brakes.

Emergency back-up system. As in planes, auto pilots etc. ... (?)

Do self driving cars know how to drive on snow and ice? If so, are they better than a typical human? Or are they safer than a mixture of typical and bad human drivers?

The only difference between being on ice or asphalt is the level of traction reached before the vehicle starts slipping or sliding. Once the limit is reached, sliding on asphalt or sliding on ice is pretty much the same and the same reactions should be expected from the driver. It only happens at lower speeds and accelerations.

If there are any differences, roll over is more probable on asphalt, something you don't really have too worry when on ice.

I agree. What I wonder about is if it would detect it and know what to do. Can it see a patch of ice coming up and know to just coast across? The more people talk about removing the steering wheel, the more significant these automated capabilities are.

The bigger issue according to what I have read is the impact on the sensors in snow and rain. Vehicles already have road condition sensing(Wet and ice), and wheel speed based traction control that monitors for slipping. Humans are awful at driving in bad conditions, tunnel vision, stress, too high speed, following too closely - etc...

It's true that traction control is good and that a typical mixture of drivers is bad on ice and snow. That being said, I'm not sure that I would want a car without a steering wheel if I was on a road with patches of ice or snow. I know that I can see the bad patch ahead and prepare to just coast across it. I haven't seen any mention of those situations when people talk about self driving cars. I would like to know what the current state of the art is.

PS. I just saw a warning to not use cruise control while driving today (snow and ice hit last night). Apparently traction control and cruise control are typically not coordinated.

 

[jack action]

The difference between a road covered in ice or not is easy: comparing wheel rpm with velocity and keeping track of the yaw velocity will give you good indications.

I guess identifying a patch of ice is more difficult. But you can still monitor wheel rpm and compare it with the vehicle velocity in a rather instantaneous way. As for looking ahead (like slowing down for a patch of ice in the curve ahead), I guess some probability of the road conditions to come can be calculated based on the road already traveled and adjust the speed accordingly, just like a human does. And, although I'm no expert in the field, if a human can see a patch of ice ahead, I can't imagine there are no vision systems that already exist that cannot detect it either and make an appropriate guess of what it is, keeping the decision process on the safe side (i.e. slow down). They are people working on such vision systems for sure.

Another way with AI, is sharing information. If one car slips on a patch of ice, the info can be sent to a central database and be available to all other vehicles passing afterward.

 

[Windadct]

sharing information

- car to car networking is a HUGE advantage - but I have never seen any info on work in this. Since the different manufacturers would need to agree on the format it needs to be agreed upon and/or set federally.

I wonder how the dynamics between driven cars and driverless cars will play out.

A driver knows that a driverless car will always demure, acting in favor of safety. So, what's to stop drivers from constantly cutting in on driverless vehicles?
Every day, I see situations in my city where driverless cars will be literally paralyzed, unmoving, as car after car takes advantage of their noncompetitive nature.

Once the limit is reached, sliding on asphalt or sliding on ice is pretty much the same and the same reactions should be expected from the driver. It only happens at lower speeds and accelerations.

Unless (e.g. sometimes in roads with large slope & ice or snow) the limit is already reached and the driver or sdc is "caught on sleep" ... with no reaction possible!
Ice and snow can sometimes be very tricky!

The more people talk about removing the steering wheel, the more significant these automated capabilities are.

IMO the steering wheel and option for manual mode doesn't hurt, ... just in case. Why remove it? I am against that, although I voted 'yes' to the poll.
(I am sure there are always cases where a human driver must override and take control, unless a perfect override and/or back-up system can achieve the same emergency or simple convenience result ...)

I should have known that Canada would take the issue of self driving cars on snow and ice very seriously:

In England we have a lot of roads like the one in this video I wonder how driverless cars will deal with the situation that occurs at just after 7min30. The camera is in a large truck/HGV..



Will there be a suitable button labelled "Give way to other driver even though I should have right of way"?

The HGV is also scrapping the bushes on either side. Would a driverless HGV allow that? Would there be a setting that allowed the passenger to adjust how aggressively the HGV pushes through overhanging vegetation?

If there are no steering wheels, this example shows that AI from each vehicle must be able to communicate with each other, just like human drivers do (sometimes just by making gestures or faces). Even if it is not the central database I was talking about earlier, there must be at least some 'local' communication.

Once vehicles communicate with each other, AI can find the best solution for both vehicles according to their needs and priorities. Stop signs and traffic lights wouldn't even be needed.

Would there be a setting that allowed the passenger to adjust how aggressively the HGV pushes through overhanging vegetation?

That is an interesting problem. I guess it would be possible, but is it desirable? Can we put a setting on driverless cars that commands: «Jump off the bridge. That's what the passenger wants.» How much damage to the car is allowable before the car says «I won't do that!» I never seen such setting on contemporary machines: It's either the 'automatic' (fail-safe) or 'manual' (do whatever you want) mode.

It can even be worse when considering snow. People here in Canada often don't shovel the snowbank in front of their driveway (lazyness) and just drove over (or through) it. There might be a hidden curb under that snowbank too. How big of a snowbank would a driverless vehicle find acceptable? That decision not only depends on the size of the snowbank, but also on the type of snow as well.

The more I hear about the challenges of steeringless vehicles, the more I think we are far from this reality.

 

[CWatters]

On some roads if an HGV didn't make contact with hedges then it would have to stop or take a different route. HGV and busses brushing hedges and trees also reduces the need for teams of people to be sent out to cut them back - or at least that's the impression I get.

Where I live, Id feel safer with a raccoon behind the wheel. Every morning commute is a dance with death. My roommate was rear ended 3 times in his first two months here.

I think in general everything (or almost) is programmable, or ... manual mode.
In the video's case: [Driver to sdc:] "At least let me do the talking! ... and please don't worry about the bushes."
(That should do it.)
