OK here's one we all see every day of the week but.....

Bunching on motorways, why does everbody do it?????

It's not too much traffic it's everyone driving like complete twats. It perfectly possible to COMPLETELY avoid it.

Just hang back, loads, LIKE 200M+, as the lemmings in front start braking just decelarate, I assume most people are not looking further in front than the other cars number plate.

I can understand doing once, but every thirty seconds, it makes me laugh.

I can drive the entire distance of the M6 at peak times without touching my brakes once, everyone else is start stopping. The average is the same though. Don't say it's impossible cos I did today, I do it nearly every day on motorways.

Other people must have stopped 100+ times in the same journey.

There's also always one (bmw) who'se up your ass to get in front & sure enough you let them through & hey their on the brakes in seconds up the ass of the car in front & stationary.

There should be a Lemming law, what do you BIB's think of this......

Yeah, when I drive like that, it has that effect on other motorists too

So what time do you drive the length of the M6? 02:00 through Brum? Like to have seen you drive it last Friday morning without braking

On motorways I find that usually the very inside lane is empty (apart from maybe a parked car every ten or so miles). I can usually make quite good speed along there...

Oh yeah, I'm from Dorset, the only county in the UK with NO motorway at all.

I will tell you what causes bunching and what is resposible for most 'tuppenny halfpenny' knocks on the Motorways.
It is summed up in this sentance -:

Brake Lights (in front),brake myself,signal and finally mirror.

What should be happening is -:

Brake Lights (in front), mirror and off gas (accelerator).

There shouldnt be any problems by adjusting your speed 'with careful use of the accelerator'.

Most people just slam on the brakes when they see the brake lights on the car in front. This is what causes bunching.

Remember, 'Quiet efficiency IS the hallmark of the expert.

I tried to tell a mate of mine that he should drive slower (than 110) in traffic because otherwise you have to use your brakes to slow which causes this bunching effect. He just said brakes are to slow you down and couldn't see the problem

The biggest cause of bunching has not been mentioned
ridiculously low speed limits and the numpties who MUST try to enforce them by driving exactly 0.0001mph under the limit in the outside lane and won't effin move.....

Tonyrec, bang on the nose as usual!!!! Too right mate!
happens here in Germany exactly the same.......
just lift off, coast and then pick up speed again, but they can't because they're tailgating anyway.......

Don't forget too, that many automatics have less engine braking effect than cars with manual gearboxes. My Wedge (3.9 V8) will slow faster on overrun than my Jeep (4.0 S6) - Streaky

Too right.

If you keep the two second rule etc. and have good anticipation you can regulate speed without brakes and not have to stop start.

You always get the muppet in the BM speeding up a foot off your bumper (also - I have noticed lately VW Passat Tdi)!

The reason being that most people think if you leave a gap someone else is gonna slip in, and that of course would be catastrophic, not.

Its also related to the average numpties psychology of driving, if you aint as far ahead as you can possbly get then you must be going slow and your going to be late, regardless.

This one mystifies me. To make it worse, my wife keeps sayign "they're braking ahead", to which I have to reply, "yes, and my foot is not on the accelerator. There is planty of room and I am slowing under control".

I read a theory recently that many traffic jams on the motorway are not caused by obstructions, but by waves of braking moving through lines of cars travelling too close together.

Of course the other big problem on British motorways is that when you leave a big gap, the twt behind you will sit on your bumper and may even try to undertake at a high speed differential to go into that inviting gap you have left ahead of you.

I thought this might cause a stir, this is why we can't have higher limits in this country, this is why the M25 system works sort of.

Education must surely be cheaper than massive building projects etc etc.

In Germany & many other Euroland countries they have 7 hours compulsory leesons on the motorway before taking a test. What do we have? **** all.

Do we need scientist's to tell us what's going on.

I bet if you diverted a load of cars off the motorway onto the Millbrook High Speed Bowl & told em to go as fast as they want soon enough they'd be stationary in sections of it.

What gets me these people are quite probably educated, clever, businessmen, you name it bright people but put them behind the wheel of car & they have total IQ bypass aaaaaaarrrrrrrgggggghhhhhhhhh. I can understand when it happens once but continually & it's always the same people accelerating into the gaps & coming to a halt.

When I see all the bunching up going on ahead of me, I try to NEVER brake, just ever so slightly slow down. I'm hoping that by doing this I'm causing the 'traffic jam wave' to stop and hopefully alleviate any congestion that appears behind me.

Obviuosly this plan doesn't work when some tw@t comes steaming up behind me and then slams on their anchors.

It's just ANOTHER case of drivers not being observant, if we all work together we could get where we want to go quicker.

I was thinking about this on Sunday as I drove back from Essex to Basingstoke around the M25. The root cause is the ridiculous tailgating people do. If you leave a decent gap you can use it to "soak up" these variations in speed with little need to brake.

It constantly astonishes me at how little room the average driver leaves on the Motorway. Terrifying!

Agreed and if you are watching far enough in front you have already started to adjust your speed even before the car three, or four, or more, infront of you has even touched their brakes.


The wave effect is true. How often do you see the line of traffic getting slower and slower as the brake lights move down the line with each person having to brake harder than the person before. All because they have not left enough room and are only looking at the car directly in front of them.

on the Motorway, Why can't they just leave a gap and use the throttle to regulate speed. It really is very easy! The more people bunch and the more accidents there are the less likely anyone is to listen to the higher speed limit argument.

Applies to The Netherlands too, that is if you define a 'big gap' as 'at least three feet more than the length of the car Mr. twt is driving'...
Then of course, he slams his brakes the very moment he's back in your lane, six inches in front of your bonnet. Like he only sees now that traffic in front of me isn't going any faster than I am, anyways. Always a nice touch, that.

I ended up in a rolling block on the M25 on Friday afternoon.

Two TIRs in lanes 1 and 2. Me in lane 3. BMW in lane 4.

Horrible traffic at about 4pm. Everyone stop starting.

The four of us simply rolled forewards at a constant 4-5 mph for about 3 miles.......

Don't know if it helped, but it was *much* easier than constant speed changes.
