Slowing down to overtake.

    I'm not referring to anyone. I'm just saying no ACC I've ever used is as slow as described in this thread. None I've never used matches speed with a car in the next lane.

    "...Adaptive Cruise Control (ACC) systems are designed to react to changing traffic conditions instantly, often faster than a human driver. They use radar and camera sensors to monitor the distance to the vehicle ahead in real-time and make adjustments to speed, including acceleration, deceleration, and in many cases, bringing the car to a complete stop. .."

    Will it simulate some clown burying their foot in the floor? Why would anyone want that....

    L plates are to let you know to have patience with a learner because they will be sloooow. So lets put leathers on a motorway to speed it up makes no sense.

    The m50 may be unique in Ireland, but the fastest way to traverse this road is, rather bizarrely, to stay in lane 1.

    Around 13 or 14 years ago we decided to visit my parents holiday home in Wexford. At that time my missus had her full licence about a year. I informed her she was driving, when she blurted out she'd never driven on a motorway. She had successfully dodged driving on the m50 even though we live beside it. Anyway, I made her drive it. 10 minutes in to the journey she asked why everyone was driving in lanes 2 and 3. 'They're idiots' I told her. 'Stay in lane 1.' It's still the same now.

    You had a bad day? Calling lads clowns for accelerating as necessary to reduce inconvenience for other drivers?

    No ACC I have used is as reactive as manual acceleration. It’s perfectly adequate when traffic is relatively light with plenty gaps in right lane traffic but does result in delays if trying to overtake slow moving traffic with 120kph traffic on right lane. However, calling it glacial is just another example of being over dramatic



  • Registered Users, Registered Users 2 Posts: 16,990 ✭✭✭✭Flinty997


    The ACC wouldn't be much good if it reacted much slower than a human. It should be better. It's engineered to be better. It's not set to mimic a racing driver though.

    It simply doesn't work in the way you've described.

    "…Overtaking Assistance (Specific Models): In cars with this specific feature:
    Ensure a vehicle is in front and your set ACC speed is high enough.
    Activate the direction indicator for the overtaking lane.
    The system temporarily accelerates the car towards the vehicle ahead to help you move into the overtaking lane, and delays braking until you have cleared the overtaken vehicle..."

    This indecisive brochure your ascribing to a computer is human behaviour not a computer. A computer isn't indecisive. Why would some one programme a delay into a adaptive system.

    I use the ACC regularly in heavy M50 traffic. Takes all the work out of it.

    I think that depends on the day and the moment. Some days lane 1 it's full of people merging and leaving, trucks etc. it's crawling. Other days it's the fastest moving lane. M25 in UK is similar. Maybe it's the nature of orbital motorway with lots of junctions in close proximity. Often all three lanes are bumper to bumper and at least in lane 1 it's easier to exit it. I'm often off at the tunnel or malahide and you have to move right and get in the right lane early in traffic.

    I've just come in from driving it and it was light traffic both ways. One guy thought it would be cool to do about 150 in lane 1 undertaking all the other lanes all the way to M1.

    The one that I find quite dangerous is truck one going at 89.9998km/h and truck two going at 89.9999km/h and they decide to overtake and make absolutely no speed adjustments. Whole manoeuvre taking anything up to 2 mins while the overtaking lane is blocked.



  • Registered Users, Registered Users 2 Posts: 16,990 ✭✭✭✭Flinty997


    On the M50 it's not uncommon for the overtaking lane to be crawling, you'd dream about 89.99999



  • Registered Users, Registered Users 2 Posts: 6,575 ✭✭✭creedp


    I know you don’t like it, but I disagree with you on this issue and no amount of dropping on definitions and what looks like AI generated content will change my view. I’m happy you’re happy though.

    As you say yourself on the M50 you’d dream of hitting 89.999km so perfect territory for ACC. There is however a life outside the M50



  • Registered Users, Registered Users 2 Posts: 601 ✭✭✭Speedline


    Have to disagree with using Active Cruise on the m50. It leaves a safe distance to the vehicle in front, which in turn invites every b0llox to cut in front of you.



  • Registered Users, Registered Users 2 Posts: 6,575 ✭✭✭creedp


    If you haven’t already you can adjust the gap to the minimum which might help as ACC is at its most useful IMO in heavy motorway/DC traffic

    Yeah I don't have it myself. The missus's car has, but I don't drive it much and wouldn't really play with the settings.

    Good advice though. Thanks.



  • Registered Users, Registered Users 2 Posts: 1,555 ✭✭✭csirl


    Doubt that most of these drivers are using ACC - they wouldnt know what it is or how to turn it on!



  • Registered Users, Registered Users 2 Posts: 6,575 ✭✭✭creedp


    😄 hard to disagree tbf. If people can’t master Bluetooth for there phones it’s hard to believe they could understand/operate ACC



  • Registered Users, Registered Users 2 Posts: 16,990 ✭✭✭✭Flinty997


    The ACC reacts very quickly to people cutting in probably too aggressively and quickly IMO. I often override it, flick it off and back on again.

    That said if it's heavy traffic letting them really makes no difference to your journey time.



  • Registered Users, Registered Users 2 Posts: 16,990 ✭✭✭✭Flinty997


    Your theory is drivers too nervous to overtake are being slow when overtaking are using ACC to overtake instead. When ACC isn't slow like a nervous driver. Also a nervous driver will not have confidence to use ACC, and not on a motorway in traffic and not for overtaking.

    "...Nervous or anxious drivers often lack trust in Adaptive Cruise Control (ACC) because it removes a sense of direct control, which can increase, rather than decrease, their anxiety behind the wheel. ..'



  • Registered Users, Registered Users 2 Posts: 16,990 ✭✭✭✭Flinty997


    No proof or facts or logic will dissuade you. That I agree with.



  • Registered Users, Registered Users 2 Posts: 6,575 ✭✭✭creedp


    I prefer dealing with reality than slavishly trawling the internet for theoretical support for your one dimensional view. For someone who demands unconditional support for your views on how flawless ACC is for the non clownish driver I’m a bit taken aback by your admission that your’re actually better able to deal with heavy M50 traffic than this flawless ACC

    I'm just curious when some says something like ACC hesitates for ages, or people need training to drive on motorways does that actually track with facts or peer review studies.

    Something like ACC is obviously subject to industry testing then 3rd party safety studies. Then theres loads accident studies on ages and accidents. Not many on motorways specifically but there are some.

    Theres a big difference between how people drive on Irish Motorways and other countries like the UK. One big difference IMO is enforcement. UK are much tougher on progress on motorways and leave discipline than in Ireland. Orbital motorways excepted.

    I can't remember ever seeing anyone pulled over in Ireland for holding up traffic. Not ever.

    This is just taking the mick at this stage. We're talking about test-ready drivers under professional instruction, not some sap who can barely get into 2nd

    There are driving schools that will do motorway lessons. You should definitely lobby your politicians to make them mandatory for everyone. Good luck with that.



  • Registered Users, Registered Users 2 Posts: 7,302 ✭✭✭Charles Babbage


    This a red herring. Motorways are the easiest place to drive, by far. You can describe how to drive on a motorway in two or three sentences. People who chose not to drive properly, including slowing down when overtaking discussed here, are doing so because they do not care. Giving them lessons will not make you care, only enforcement will.



  • Registered Users, Registered Users 2 Posts: 16,990 ✭✭✭✭Flinty997


    I made the same point earlier. My post was in jest.



  • Registered Users, Registered Users 2 Posts: 7,302 ✭✭✭Charles Babbage


    I perhaps did not read the whole thread. But some people do not seem to see the bleedin' obvious.



  • Registered Users, Registered Users 2 Posts: 6,575 ✭✭✭creedp


    The only enforcement on Irish motorways relates to speed. It’s easy to enforce and for some people is the only cause of problems on Irish roads. Some people get weak at the knees about people doing 130kph on a motorway but have no problem pottering along at 80 kph on the outside lane with no traffic on the left or driving along on the outside lane and diving across lanes just before an exit causing mayhem for everyone else.

    I think we are also the only country in Europe that allows 50kph agri tractors to potter along on motorways causing a rolling roadblock everywhere they go.

    Less of an obsession with speed and more on actually proper enforcement of the other rules that make motorways safe would sort out a lot of the messing currently to be found on Irish motorways



  • Registered Users, Registered Users 2 Posts: 16,990 ✭✭✭✭Flinty997


    That's quite the obsession with speed right there…

    Across Europe they have variable minimums it can go very low for bad weather and road works for example. Going to work out badly if you can only drive at the maximum.

    Only enforcement on speed? Theres statistics of points and offences from the courts etc.

    https://www.rsa.ie/docs/default-source/about/penalty-points-statistics-august-2024.pdf?sfvrsn=b3fb06b2_3

    Tbh I'm surprised at the volume. Hardly ever see enforcement especially for speeding.



  • Registered Users, Registered Users 2, Paid Member Posts: 41,281 ✭✭✭✭Hotblack Desiato


    Totally irrelevant as it covers all roads not just motorways. Any garda on foot patrol or in a car can issue points to drivers in a city or town if they happen to observe an offence, on a motorway it's only the dwindling Roads Policing division who can act

    2 mins? I got stuck behind 2 trucks doing exactly this about a month ago on the M7. Were already at it by exit 15 and still hadn't cleared by the next exit.

    It used to be that truck drivers were among the best on the roads. Not so anymore!

    Both on the limiter with one slightly more generous than the other…

    You can cut your fuel consumption by 40 or 50% by staying behind the trucks on the motorway though. And I don't mean following at an unsafe distance either.
