Intelligent Speed Assistance (ISA) to Become Mandatory in All New Cars in The EU from July 2024

Looks like those crazy Euopeans are at it again… (And I thought we needed a break from "I received a fine…" and "I had a crash…" posts)

I made a previous post about the EU making suggestions about mandatory black box recorders for new vehicles. Well, it seems as though they have gone and raised the bar and are now making Intelligent Speed Assistance a thing.

"What is ISA?" you may well be asking. It is a system that relies on GPS and visual readings of road speed limit signs to "encourage" drivers to drive within the speed limits. This encouragement can come in a variety of levels, from an audible warning, to haptic feedback and finally the car's ECU taking over the throttle control and "pushing back" against the drivers attempt to go faster.

I see a few issues with this, namely my wife's Corolla has speed limit sign recognition, and let's face it, it's crap. I have been in areas that are obviously 50km/h and it still reads the last sign it saw at 80km/h, or, I have been entering onto the freeway and the car hasn't picked up on the 110km/h sign and still reads 80km/h. Imagine trying to ramp up to 110km/h and having the car fight you the whole time to keep you at what it thinks is the speed limit…

So, is this government over reach into our lives or is the population just getting so bad at driving that we need to hand over most of the driving functions to computers, or maybe this is just one step closer to autonomous vehicles where we are just merely a passenger and not a driver…

Another knock on effect that could happen is, with this technology, what are the police going to do when everyone's car is doing the speed limit?

Let me know, good idea, bad idea, Would you put up with a vehicle that wants to make too many decisions for you??

    This is going to open a ‘can of worms’!Not to fond of this idea!Should imagine this will not go down well in Germany, we’re the Autobahns are unrestricted speed limit.

    • +7

      Autobahn has a recommended speed limit of 130 and there are insurance implications for going over that, pretty much a do at your own risk. ISA is much like that too.

      Automated driving will be the norm one day, computers will eventually be better drivers than humans since they can have more senses, not get distracted, not get drunk and crash their brand new Jaguar because they think they've made it being the shadow AG of Victoria. Slow introductions like this is a good idea, to get people more and more used to it. If it can save lives all the better, we don't have some kind of constitutional right to drive however we feel like.

          Speed doesn’t kill. Sudden deceleration does. Speed just increases the risk of having an incident where sudden deceleration occurs and increases the amount of energy that deceleration transfers to a body.

          • @Euphemistic: Speeding also removes you from the mass of predictable road users. Road users expect others to behave in certain ways. Once you start behaving in unusual ways (through any form of poor driving) you've increased the chances of causing an incident.

            @Euphemistic:

            Sudden deceleration does

            Actually stopping kills, the sudden stop, not deceleration.
            Parachuting players know that. From free fall to gentle fall. And they survive.

                  @LFO: You also don’t need to stop to decelerate hard enough to cause injury. Run into the back of a truck moving at 40km/h at a speed of 140km/h is a sudden deceleration that would likely kill you that doesn’t involve stopping.

                  Stopping is changing from your initial speed decelerating it to zero. The quicker you change your speed, the more damage. The sudden change of speed requires some sort of force which causes a squishy body to deform. Your body can with stand a few g of deceleration. Much more and you’re in trouble.

                  But it’s largely semantics.

                    @Euphemistic: It works the other way too.
                    That's why Space Travel is difficult because the rockets have to gradually add the forward acceleration. If it's too sudden then you also get "cosmonaut smoothie" or at the least serious injuries.

                      It is gravitational forces the culprit, not speed nor forward acceleration.

                        Also unlikely to get injured by going from 120 to 20kmh

                        C'mon, say it "it is the sudden stop what kills"

                          That just depends how fast you decelerate. As example above if you hit a truck that is at 20km/h and you’ve been travelling at 120km/h you are pretty likely to get injured.

                          Or go stand in front of a moving bus, the injury occurs when you suddenly move from stopped to 60km/h stuck to the front of the bus.

                          C'mon, say it "it is the sudden stop what kills"

                          Pretty sure sayings aren’t an accurate description of physics.

                            Well you are actually stopping when hitting the truck.
                            The truck will always be on your face, as when stopping.
                            If the truck or the planet earth moves does not not impliy you have not stopped.

                              you're calling stopped when a 'body' in motion goes from 120km/h to 20km/h… not sure you want to be using the word 'accurate' in your description of physics if that is your logic

                              The ground speed is the reference in the given example as that is what your velocity is in reference against.
                              You go from 120km/h to 20km/h by running into the back of a moving object at 20km/h, the resulting forces are due to a change in velocity from 120km/h to 20km/h. You dont 'stop'. Your frame of reference goes from 120km/h to 20km/h

                              Change the numbers to make the example easier….. If the truck was going 119km/h and you hit it at 120km/h…. Do you stop, or does your velocity decrease (and resulting impact force) by 1km/h?

                            • @LFO: No. You don’t stop if the other item is moving at 20km/h. You end up going at 20km/h (plus whatever change in speed you cause the truck by adding 120km/h worth of energy from your mass). You decelerate by 100km/h almost instantly, you don’t stop.

                              FWIW I have only applied one neg vote to any of your replies here.

                          the time of deceleration is important.
                          How can you argue about the resulting forces on an object from a change in speed, unless you include the time period for that change

                          120km/h to 20km/h over the period of an hour… thats slow
                          in 0.5 sec, well…thats a force of ~5.5g

    not sure 'fighting' is overstating it enough ;)

    The ISA system is required to work with the driver and not to restrict his/her possibility to act in any moment during driving. The driver is always in control and can easily override the ISA system.

    having the car fight you the whole time

    it will push the driver’s foot gently back to make the driver aware and help to slow down. The driver can ignore this feedback and override the system by pushing slightly harder on the acceleration pedal

    Having seen the quality of drivers out there, the more smarts within cars the better.
    Even a Haval is likely smarter than the average driver these days ;)

    • -1

      I remember last century discussing the need for cruise control to be smarter. I was told that cruise would never interfere with braking, as it would be too dangerous.
      Finally people have seen the light and active cruise is so much better.

      Ultimately we'll get councils and transport departments to lift their game so that vehicles can get reliable information, then we don't want it turned off.
      In my future, I'd like to see driver's need to lodge an explanation if they override the vehicle's controls, so that manufacturers can examine any shortcomings and/ or the driver can get a ticket.

      We need to take some functions away from average (and below average) drivers: merging onto highways, changing lanes, highway overtaking lanes,…

      • 'active cruise is so much better'

        yeah I loved it with a rental car in Germany - with stop'n'go, I could set the cruise to 220kph, and it would automatically do that auf den Autobahnen when traffic allowed, slow with vehicles in front, and stop as required at roadworks, then automatically start off again as available - I could go for hours without touching any pedal

        I believe Toyota's 'active' cruise requires repressing the throttle or something after stopping ?

        and only a few models like VW, Merc, BMW in Australia actually have the full no-touch stop'n'go cruise control as I enjoyed - frankly I wouldn't bother with anything less.

        the one annoyance was turning off tight off-ramps where a slow vehicle in the other lane would come into view of the narrow radar, which would be interpreted as my lane, whereupon it would slam on the brakes hard - I had to learn to turn off cruise control on tight bend offramps.

        • My 2015 Mazda is the same with the 'no-touch' active cruise. On the same car, you also override the braking part of active cruise just by lightly applying throttle.

        • The Kia requires accelerator or restart cruise after a complete stop. I agree I'd prefer auto restart, but I can imagine the problem of the driver forgetting the car is still in drive and is in the backseat or glove compartment or something when the car in front turns and allows yours to enter an intersection.

  • +1

    As long as there's training to understand the feedback given by the car, and will the feedback be standardised across manufacturers?
    Also there's a problem with people losing driving and awareness skills and relying on automatic systems.

    • People here aren't going to like it, but driver monitoring is also required.

      Too many lives are taken by inattentive drivers (this doesn't just apply to autonomous vehicles, but will surely get worse).

  • i wouldn't put up with it, in fact i still have to go and turn off the speedometer in my dashcam as it is about 10 ks off what my speedo is saying, but if i ever got in an accident, the insurance could look at it and say i was speeding, when my speedo would be reading 10 ks lower.

            speedo shouldn't be indicating a speed slower than i'm actually going, for example it should not say i'm going 100 if i'm going 110

            it is allowed to say that i'm going faster than i am actually going, for example it's allowed to say i'm going 110 when i'm only going 100

            i made a mistake in other comment, i meant that speedo shouldn't be off in that direction (reading slower than i'm actually going)

            though having read that, my car is pre 2006 so i'm not sure if it has to follow the new rules

            • @[Deactivated]: That's very odd, GPS isn't perfect but it shouldn't ever be consistently reading x km/hr above your true speed, rather fluctuating up and down. The nature of GPS and how it calculates position means it's very unlikely to consistently overestimate your speed. Also can't see any plausible reason the dashcam manufacturer would intentionally increase the displayed speed. All of that said, I'd image you'd have been getting a lot of tickets if your speedo really was reading 10km/hr under.

              Probably be a good idea to check your true speed using mile markings and a stopwatch.

              • @nigel deborah: from what i've heard, Tas police are a lot more lax about traffic violations than the mainland, and we only have a few speed cameras around, maybe i've just been lucky if my speedo really is reading 10 ks less than i'm going,

                having said that, if my speedo really is reading incorrectly, then the majority of people around me are speeding, as most either keep up or go faster. i admit i've had a few times when i just could not be bothered being stuck behind some idiot who constantly fluctuates their speed between 110 and 90 so i've sped to get past them and stay ahead as they always sped up when we got to double lanes, but then when i've been going that fast, i've had people going past me at even higher speeds, i swear one guy i saw in a dual cab had to have been doing at least 130

    I was thinking, what if the insurers get a hold of this data; for the safe drivers whom are able to maintain the speed limit they pay the regular rate and then have a risk based system for drivers who exceed speed limits.

    Or, my current insurer requires I specify how many times per week I drive to work/train station and if I drive in peak times etc. If it's a automatic calculation (weekly) great but if they have any wiggle room not to pay, they won't.

    • Gee, which insurer is that? I'll get a quote from them for my car, which does hardly any k's in traffic. I've long wanted insurance premiums that tries to adjust for how much distance in traffic it covers.

      I know a lot of people may disagree with me, but there are certainly times where speeding is the safer option.

      I drive a lot for work, and often on shitty, narrow lanes with a lot of truck traffic. These guys often swerve, invade your lane, or come close to hitting you. Slowing down to create distance isn't always the best option, and at those times, it's better to speed for a few seconds to get away.

    • Quite the opposite. The hooligan is trying to ram you, but these new ISA will slow him down, so you will smile and drive on.

      • I wish I was smart enough to think of comebacks like these

    • +1

      Completely misses the point. These systems WARN the driver if they're speeding (via haptic feedback, an alarm, whatever). They prevent unintentional speeding, not deliberate speed.

  • +2

    Not sure I super agree with it, maybe if the solution was to give you a heads up on speed or something I get it. I would actually love an official thing to tell me what the speed limit is on the road I'm on. But as someone who lives regionally a lot of the time, most of those GPS stuff suck. They miss so many roads, basically never get updated and many times will calculate weirdly. My house legit doesn't even appear on Google Maps, and I've tried some GPS that don't have it.

    Then comes the auto speed, typically after some time I see many electronics in cars start to fail, to me this feels like another point of failure in 5/10 years time. I also imagine it would need to be updated very regularly, again living in the country you don't get much internet going around.

    Then is the problem where it sort of tries to slow you down as well. This is another problem I see, due to the long roads I've had trucks up my ass going +110KMH (legal limit is +100KMH I think for trucks?) as many have strict deadlines. Last thing I want is for a random slow down at a speed sign they may or may not be updated or broken or removed while infront of a road train.

    I get the idea on paper, but I would imagine theres even more problems then I came up with for real life use.

    • These systems only ever give you a "heads up on speed", though admittedly they are sharper about it than just a beep (eg vibrate the throttle pedal, a voice calling out "speed speed speed"). It's the same approach as used in aviation (stick shakers, terrain and collision avoidance systems, etc). They don't slow you down in an emergency.

      All they really do is get rid of the "sorry officer I didn't know I was speeding" excuse. And get fewer whinging "I woz fined by a revenue raiser and it aint fair" posts on Ozbargain.

    I have been entering onto the freeway and the car hasn't picked up on the 110km/h sign and still reads 80km/h.

    I’ve had the reverse. Travelling along the freeway at 110 and the car picks up the off ramp sign at 70, then doesn’t revert to 110 until the next sign.
    Although, I could conceive a GPS mapping enabled system, not a dumb sign reader, would work out quickly that you didn’t take the off ramp.

    • or those roadworks sites where the speed limit changes 56 times in 5 kms…

    This will only make people less capable at driving as they start to rely on the aid to tell them to slow down instead of them paying attention to their surroundings. Kind of like how a heap of idiots can no longer reverse a vehicle unless it has a reverse camera.

  • I already have ISA on my car. It's not that big a deal really. When it's on it will try to slow you down by limiting acceleration to bring you down to the speed limit but you can override it by accelerating more. The cameras that detect speed limit signs are incredible accurate, I was really surprised. The main problem is things like school zones where it thinks it's 40 all the time. GWM Cannon L ute.

    All part of the great reset. You will have a carbon emissions passport. You will have an annual limit and everything you do will be tracked, from the food you eat to the type of transport you use. Once you use your annual quota you can purchase carbon credits or go without. They will also tax you per km travelled.
    And if you don't comply they can shut down your car.
    No, it's not a good idea.

      They already do that by taxing fuel (the more you travel, the more you need, the more tax you pay). And if you don't put fuel in your car, your car will shut down!

      oh god, what next

      they'll start taxing income, and the more we earn, the more they'll tax us
      and then they'll start taxing consumption so you can't hide money
      and then they'll start taxing petrol so there's a link between how much you pay and how much you drive
      and we'll have some sort of "tax file number" and a big government agency to keep track of it all
      and we'll have special cards with the mark of the be…I mean, special chips to spend money
      and we'll willingly carry electronic trackers in our pockets that connect to the phone network

      oh wait it's been like that for decades

      Oh course these limits won't apply to the Brahmin left (ALP/Green politicians + Unioned government employees + academia). They will continue to fly everywhere in private or chartered planes and drive huge luxury SUVs and live in climate controlled mansions.

  • All the issues you have stated are going to exist in existing tech like Tesla's autopilot. still it has not stopped people from using it.

  • With all the prophets of doom here predicting what it will be like in the future, here's something that has already arrived.

    Certain places in the US already have smart number plates. Instead of being stamped with your car's registration number they display it on a screen. They are also GPS and mobile phone network connected. So you can set them up to display, say, your company's logo. But also, if your car is stolen then it can display that it is so everyone, including any passing police, can see that immediately and stop the car, or report its location if it is dumped so it can be recovered quickly. Everyone's waiting for someone to figure out how to hack them. It'll be fun when that happens.

    Remember they told us all in their expensive "road safety" education campaigns that distracted driving was such a big problem that AI-controlled overhead cameras were vital and necessary to detect people using mobile p[hones while driving, along with lots of demerit points and a big fine? And they weren't really doing it because those cameras generated lots of big fines, honest, I'm sure a lot of people believed it.

    Well, the first research has come out on what is causing the significant increase in distracted driver crashes in recent years. Its from the US, where the same thing has occurred, but there's no reason to believe the causes aren't the same here. And in the US the numbers of road deaths are big enough that they get to sizes that can give statically significant results faster.

    To everyone's surprise the numbers showed the problem was NOT mobile phones. They contributed to 13% of the 7% of fatalities that were the result of driver distraction. That is, to about 1% of total fatalities. So the cameras and the penalty points and the fines are likely to have an insignificant road safety benefit.

      Just because something doesn't lead to death (as much as other causes/reasons) , doesn't it's no big deal and control measures are not necessary.

    I've seen some spectacularly poor driving in my life, even at / below the speed limit. In fact, it's usually those who have no idea how to drive so they go 20-30 under the limit, bouncing around in their lane, that cause the most problems.

    I honestly can't see this making a big difference to the number of people who die each year on our roads. Plenty of other things that can be targeted like driving tired / drunk, inattention like mobile phones, radio, etc. or just overall a poor understanding of road rules or how to operate a motor vehicle which will have a real world impact.

      Of course it won't make a big difference to the number of people killed each year - especially as the whole point is only to stop people speeding without knowing it. Hoons can still hoon to their heart's content because it doesn't prevent deliberate speeding - only discourages it by inconvenience (a warning voice, a vibration).

      But it'll make a modest difference. That is worthwhile.
