Listening to a news article this morning got me thinking..
..how soon would it be before mischief makers in other vehicles
muck about to set-off collision avoid sensors etc.. on these vehicles. ____________________ Now: A100, GT250A, XJ598, FZ750

It's not just that, I consider myself a very judge of what people are going to do next on the road, I doubt a car would ever reasonably be able to do that based on slight inputs like the car ahead subtley altering lane position or similar. I don't see self-driving cars being anything more than reactive for some time yet. |
I'm not so sure; your judgements aren't based on extra-sensory capability (unless you tell me otherwise) but rather an accrued understanding of indications which manifest into behaviours, e.g. someone slowing slightly before a junction might suggest they're going to turn, or moving closer to the centreline might indicate they're considering an overtake. I don't see why a computer could make those same judgements and indeed pool an even greater amount of effective "experience"?
What a computer would struggle more with though might be more subtle things, like someone stabbing at a phone showing a nav screen, or kids flying around in the back causing a distraction.
As I said, in theory the computer can make a good decision, but what it can't do is interpolate where it doesn't have the facts, something the human brain can do (albeit not always with the correct outcome "I was sure they weren't going to do that"). ____________________ TG. |

This will be an interesting debate:
https://www.bbc.co.uk/news/technology-60126014
Major legal changes needed for driverless car era
Human drivers should not be legally accountable for road safety in the era of autonomous cars, a report says.
In these cars, the driver should be redefined as a "user-in-charge", with very different legal responsibilities, according to the law commissions for England and Wales, and Scotland. ____________________ DILLIGAF |

The human fuckwit factor is still real, even at the design stage.
My Dads Jag E-type has a very reduced view out of the rear window. That's ok though because it has a superb reversing camera.
It also has reversing sensors.
If the reversing sensors are triggered, a beeper sounds and a message is displayed across the middle of the screen warning you to take care when reversing. Unfortunately, the message totally obstructs the image from the reversing camera and will not go away until whatever is triggering the parking sensor is out of range.
He has already reversed into two cars as a result of this.* Two safety systems working together to make you crash.
I suppose the main issue will be how does it recognise a failure state and what happens in that situation? My suspicion is it will be much like traction control and ABS. In that it stops working beeps and a light comes on on the dash saying it's not working. As you plough through a hedge or bus queue.
*Yes, he also has side mirrors and I did dare to mention this but I won't do again! ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

Here's the rub. You need to make some autonomous vehicles slightly aggressive and some slightly cautious.
There are cautious drivers and aggressive drivers. So taking the example of pulling out of a junction. When there is a car coming along the main road, at a certain point, some drivers will wait for it to pass and some will accelerate quickly to get out ahead of it. If a computer learns and tries to do what the average driver does, they will crash the car.
So you have to incorporate a randomness factor in the vehicles behaviour and the vehicle needs to behave like either one or other sort of driver, not both and definitely not halfway between them.
It's tempting to say they should all behave cautiously, but I think the roads would actually grind to a halt if they did and there would be massive queues at roundabouts. You sometimes need an aggressive driver to break the traffic flow on a roundabout where one road is carrying more traffic than the others. ____________________ “Rule one: Always stick around for one more drink.

A car can have up to 4 or 5 occupants.
You're an AI and you're about to crash, and the crash is unavoidable, and you can only choose between crashing into a car or a bike. Your vehicle has the highest priority humans inside it, especially the one in the front. If you crash into another electric car, there's a possibility that everyone will go up in a ball of flame. Both your car and the other. Therefore, it makes sense to directly and purposely ram the bike, right? Minimal damage, all occupants safe and unharmed. The rider will die, but that's all taken care of by insurance and is not the AI's concern. |
That's dangerously close to Asimov's first law. You know, that Asimov that you said wasn't relevant?
The differnence is that teh robot in Azimov's universe would have been driven to cataplexy by the injury to the person it chose over the others. ____________________ trevor saxe-coburg-gotha:"Remember this simple rule - scooters are for men who like to feel the breeze on their huge, flapping cunt lips."

I'm not so sure about this; that disparity exists because of people's confidence levels, ability to judge speed/distance and their understanding of their vehicle's capabilities. With appropriate sensors (which an autonomous car would have) it would know exactly how much time it'll take the approaching car to arrive and would either wait or go in a very binary fashion. You'd have no dawdling but nor would you have vehicles pulling out with insufficient space/time causing the approaching vehicle to change speed/direction to compensate.
In theory (yes, that word again) the vehicles would communicate their positions, speeds, intentions etc. with each other and could make minute adjustments to optimise traffic flow. Obvious example is on a motorway, vehicle in lane 1 detects a merging vehicle, reduces speed by 2mph to allow that vehicle to smoothly merge, rather than maintaining the same speed, then the merging vehicle having to squeeze in and causing warning lights in the following vehicle. ____________________ TG. |

Two posts so far on this thread giving me the disturbing impression that people think traffic travelling on a motorway is somehow required to adjust their speed to facilitate merging of traffic joining from a slip road...
This is all down to the joining traffic, they have to give way to traffic on the motorway. If this means stopping when they get to the end of the sliproad because there is no space to merge, that's what has to happen. If you're driving alongside me on a sliproad when I'm in lane 1 and there's traffic alongside me, you're either gong to have to speed up or slow down. If you haven't found yourself a space before you run out of sliproad, there's no point sounding your horn at me, it's you that's wrong. ____________________ “Rule one: Always stick around for one more drink.

Indeed, my Skoda has gone full retard randomly a few times due to the "safety" features. Lane Assist picks up all sorts of marks on the roads and tries to move me. Brake Assist has on a few occasions slammed the anchors on for no reason. I can only assume the sensors have assumed something is a imminent danger.
Skoda also make it a PITA to turn them off. |
Never having driven a car with lane assist, how do you mean, tries to move you? Does it physically drive back into the lane or nudge the steering wheel or what? I can see it being very distracting. |
I've driven a couple of different variations, one that 'vibrated' the wheel if you inadvertently strayed out of your lane, another that gently applied opposite lock to try and move you back.
If you don't know it's there it is, to say the least, disconcerting and it can't differentiate between a genuine error on the part of the driver, or a considered manoeuvre.
For example, I was in a Peugeot on a dual carriageway and approaching a roundabout. Because I was the only vehicle on the road and I was pressing on, I straight lined the 'corner', which the car decided was me changing lanes without indicating and started pulsing the wheel, to the extent I thought I'd had a blow out, until I went back into my original lane and it stopped.
I didn't know the car had lane assist and it really threw me, luckily I found it also had an off switch, so that got pushed pronto. ____________________ Things get better with age; I'm close to being magnificent........

My car has three levels of driver assist. On max it steers itself, vibrates the seat and beeps. On medium It doesn't steer
but does the other two and on minimum it just beeps when you cross a line without an indicator on. I have mine set to
beep only. It also has auto braking but thankfully it can be switched off and instead if you get what the system deems as a bit
close to another vehicle it beams a huge BRAKE!! message up on the HUD. I've had this flash BRAKE!! at me a few times
and would have likely had an incident had it slammed on the anchors. I learned to drive in London so I'm quite used to getting
a bit close to stuff. It also beeps the front parking sensors if I get too far up the car in fronts arse when crawling in traffic. ____________________ Currently enjoying products from Ford, Mazda and Yamaha

I had it on a Vauxhall courtesy car, and it tries to resist you turning the wheel to be able to cross the lane. You can force it but it feels like something is definitely wrong. The first time it happened I thought the power steering had broken or something and I was looking for the hard shoulder till I realised. I fucking hated it. And you could turn it off, but it would come back on every time you started the car. No.
My fundamental problem with the AI driving thing (and lane assist), is that either I'm in control of the vehicle (practically and legally), or I'm not. I'm not up for halfway houses. If I'm in control, during normal driving, I want to be in total control, and I want automatic assistance to kick in only when conditions are extreme, like ABS, airbags etc. If the AI is in control, I don't want to be responsible for what it's doing, at all. I want to go to sleep in the back.
A situation where the AI is supposed to drive, and the driver is supposed to watch it like a hawk in case it does something stupid, is just the worst of both worlds. There's no way I could concentrate on watching the AI drive the car for hours at a time, even if I wanted to. ____________________ Current - '94 VFR750FR, '00 VFR800FI Previous - '10 Street Triple R, '92 MZ ETZ301, '05 TTR250, NSR125R, KMX125, "Honda" Win (chinese copy of an old Honda design with a C90 engine)
