Slowing down to overtake.

    I've noticed relatively recently that on the motorway there are drivers who will pull into the overtaking lane in order to overtake a slower vehicle and then they will slow down so that it takes them longer to get past it. Then they eventually pull back into the left lane and speed up to 120kph again!

    Maybe this has been going on forever but it seems to be a recent phenomenon. I've only been driving a vehicle with cruise control for just over a year so it's possible that this has something to do with this coming to my attention. My speed is constant so changes in the speed of other vehicles are more obvious, maybe?

    These are my theories for why somebody would drive like this:

    1. They enjoy hogging a lane and forcing others to slow down. (Unlikely, but we can't rule it out.)
    2. They are slightly nervous drivers and the sensation of passing a slower vehicle makes them feel like they are speeding up, even if that's not the case, so they slow down. (The most likely explanation, I think.)
    3. They are curious about the lives of others on the road so they can't help taking a long look at other vehicles as they pass.

    Has anybody else noticed this? Or is there anybody here who is aware that they do this and they can explain why it happens?

    I wonder if some people might get nervous that the car they're overtaking could change lanes. I know I do, but it makes me accelerate past them more quickly, even if that means exceeding the posted limit.

    I usually try to carry out the overtaking manoeuvre as quickly and safely as possible.

    I think that's probably fairly normal procedure.

    As you say number 2 is probably the most likely explanation for hesitancy.

    The fact that learner drivers can pass their test without ever learning how to drive on a motorway may be a contributory factor.

    Are you sure the vehicle passing out slows down....because I've found there's an increasing number of cars that are cruising along at 100/110kph, you go to pass and they increase speed and for a few minutes you are cruising at max speed limit alongside them until they finally reduce their speed and you can continue passing out.



  • Registered Users, Registered Users 2 Posts: 1,609 ✭✭✭NewClareman


    I find this all the time, particularly on national roads. A car will be doodling along at 80kph then speed up when there's an opportunity to overtake. THEN they slow right down, when passed…

    While you observe this behaviour, what lane on the motorway are you in yourself?

    is this not a motors forum topic rather than commuting & transport?

    Generally when I see this happening it's when I've been cruising behind a car for a while, neither gaining on them or falling behind them. Ahead is a slower vehicle, maybe a lorry or something. The car in front of me pulls into the overtaking lane and a few seconds later I do the same thing. Then suddenly I find I have to brake or quickly adjust my speed because I am now rapidly pulling closer to the car I've been following at a constant speed up until then. I'm in cruise control, so my speed is constant, my speed is not affected by the lorry I'm overtaking or the car in front of me (until I have to slow down to avoid getting to close to the car that has moved into the overtaking lane). The more crowded the motorway is the less likely it is that the circumstances arise, but it has happened often enough that I know I'm not imagining it.

    People can't drive .

    Like the OP I sit there in cruise control and it happens all the time on the M8. I do 45k per year so when I say happens all the time, I mean a number of times per week.

    Another odd observation is when cruising along at 120 on cruise control I come up behind a slower vehicle, pull into the overtaking lane and as I pull up beside them they oddly increase the speed to 120 as well. We're then side by side until either they slow down or I increase the speed to 122/123 just to complete the manoeuvre.

    They tend to then slow down again and before long they disappear in the rear view mirror.

    Both of these occurrences happen regularly. So so odd.

    I was on the M1 this morning when the cars in the outside lane slowed down to just under 100kmph. I was the last in a line of about four or five cars.

    The lead car pulled onto the inside lane and we all passed. I then moved to the inside lane and looked in my rear view mirror. The car holding up traffic had again moved to the outside lane even though no traffic was on the inside lane ahead of them. They clearly preferred to drive on the outside lane at 100kmph under they came under some pressure to move over.

    The mind boggles.

    So I'm not imagining it! That's good to hear. If nobody else had chimed in here I would have had to consider the possibility that either I'm losing my mind or there's a countrywide conspiracy against me!

    I think the thing of cars speeding up when you pass them is sort of the other side of the same coin. It make sense, in an instinctive sort of way, to measure your speed by observing how fast the scenery is moving past the windows rather than what the speedometer says. Another vehicle moving at a different speed will affect your estimation of your speed and it's very easy to speed up or slow down subconsciously.

    Still, I really don't get how you can do 120kmph for ages and then slow to 85kmph when passing a lorry and not wonder why there are cars stacking up behind you. I just don't get it.

    This is a constant occurrence. They hog the overtaking lane, eventually move over, and then straight back into it once you have overtaken them. I had it the yesterday heading to Belfast, except the van refused to move over, 6/7 cars eventually passed on the left, and he still stayed in the overtaking lane. Doing a sedate 110km. Issue is zero enforcement of this, some drivers are clueless, and some, like this one are just plain cnuts.



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


    Power past them. Don't give the fcukers the opportunity to speed up. I find that the type of drivers that speed up, always slow down again once you're past them.



  • Registered Users, Registered Users 2 Posts: 1,090 ✭✭✭blackvalley


    Aw those pesky “ people “ again who always seem to annoy and get in the way of all the “ really good “ drivers . Who the heck are they I wonder 🤔



  • Registered Users, Registered Users 2 Posts: 16,975 ✭✭✭✭Flinty997


    Can't say I've really ever seen this. Someone goes slower when overtaking.



  • Registered Users, Registered Users 2, Paid Member Posts: 19,330 ✭✭✭✭elperello


    The "people" are -

    1 an older cohort of licence holders who started driving before most of the motorways were built.

    2 a younger group who got licences more recently but never had to drive on a motorway to do so.

    Putting it bluntly these "people" are winging it.



  • Registered Users, Registered Users 2 Posts: 2,078 ✭✭✭PGE1970


    Do you really think that people using the outside lane as their usual driving lane is good practice?



  • Registered Users, Registered Users 2 Posts: 16,975 ✭✭✭✭Flinty997




  • Registered Users, Registered Users 2 Posts: 16,975 ✭✭✭✭Flinty997


    We've had motorways for 43yrs. Anyone who started driving before they were built has 43 yes of experience of them. Anyone who worked in the UK has 60yrs experience.

    Bit of rational thought is required here. Theres people of all ages who are simply have different levels of driving abilities.

    Do you think that someone using the outside lane as their normal driving lane is good practice?



  • Registered Users, Registered Users 2, Paid Member Posts: 19,330 ✭✭✭✭elperello


    But a lot more were built from c.2000.

    Very few car drivers have had any training or lessons on how to drive on a motorway.

    I agree they have different levels of driving abilities but the overall level of ability is low.



  • Registered Users, Registered Users 2 Posts: 1,090 ✭✭✭blackvalley


    Absolutely think that it’s very bad and dangerous practice and I wish all those “ other people “ would stop doing it and stop annoying all us “ really good “ drivers. 🙄



  • Registered Users, Registered Users 2 Posts: 16,975 ✭✭✭✭Flinty997


    I remembered I have seen this. Usually on m fast rural roads. Less so on motorways.

    Tail gaters particularly in bad weather who can drive as fast as the person they are following. Because they just follow the car in front. Like a lemming.

    But once in front they've no one to follow or pace them, so they slow down.

    Worse they blindly tailgate a better handling car and better driver into a corner then suddenly realise that they and their car can't take the bend at the same speed. They lift off mid corner and scare the life out of themselves.



  • Registered Users, Registered Users 2 Posts: 3,641 ✭✭✭Bogey Lowenstein
    That must be Nigel with the brie...


    I have encountered those types. They sit right up your hole but won't overtake you when they get the chance. When you speed up they do too. When you slow down they follow suit.

    Too chicken to drive the road on their own, as you say, afraid of meeting oncoming traffic. They would rather stay up your hole and watch your brakelights instead.



  • Registered Users, Registered Users 2 Posts: 16,975 ✭✭✭✭Flinty997


    Exactly I force them to pass then they slow right down.



  • Registered Users, Registered Users 2 Posts: 16,975 ✭✭✭✭Flinty997


    2000 is a quarter of century ago. 25yrs of driving.

    The issue is not the ageism your fond of. It's the lack of enforcement of the rules. People can drive like a clown and never get pulled over.



  • Registered Users, Registered Users 2 Posts: 16,975 ✭✭✭✭Flinty997


    Good practice for what? NASCAR?

    It's an offence not to keep left.



  • Registered Users, Registered Users 2, Paid Member Posts: 19,330 ✭✭✭✭elperello


    25 years of doing something the wrong way isn't much to be proud of.

    My post was definitely not ageist.

    I said the problem exists with both young and old drivers.

    I agree more enforcement would help but we really need to get people to do the right thing when no one's watching because you won't have AGS around every bend in the motorway.

    Saying it's not ageist and then selecting two groups solely on age IS Ageisim.

    "...people aged 25-49 account for the highest total number of road fatalities in the EU.." That is based on data not age.

    The whole point of enforcement is to make people change their habits. Human bad habits rarely change if there are no consequences. If people fear enforcement they'll drive better more of the time.
