Failing to make sufficient progress - i.e. driving too slow, is cause to fail a driving test

Try reading the thread, already discussed previously (and not as clear cut as you make out).

Thats more like it, can't disagree with any of that.

I really wanted to know what trick i was missing, i maintain my brakes to the Nth degree and always have, used to fit Ferodo pads when they were available common place because they gave a much softer pedal with better feel and werent so abrasive to discs as standard OE Textars and such of the time.
Still replace discs way before others would (never needed drilled/grooved except maybe on one fast 90's Rover the brake friction area of which simply wasn't enough for the speed/weight) and remove pads for thorough examination and the usual clean/lube of the calipers at the same time, regular fluid replacements.

Having worked on many other's cars in my time it's astonishing the neglect that brakes see, and the poor standard of some mainstream dealer maintenance where people can be bothered to get the car serviced at all.

I couldn't see how another car given the equal status could necessarily outbrake a well maintained well designed in the first place car on the point of lock up of all 4 wheels.

Yes the variables have it, thankyou.

No worries, i enjoy a constructive debate :beer:

As can brake fluid, in addition to brake fluid degrading over time and potentially becoming hydroscopic, lowering the boiling point redcucing braking effort.

Pedandry alert!

It's hygroscopic, not hydroscopic.

And brake fluid doesn't degrade and become hygroscopic, it's hygroscopic to start with, which means it absorbs water and thus degrades.

Lol :rotfl:

Fair point, I got the "g" and "d" wrong in hygroscopic, although we are in agreement that it absorbs water and reduces in it's effectiveness.

I stick to the road's limit or 10% above it (30-33, 40-44) everywhere but the motorway, where I idle along at 55 mph behind the lorries. I do often get lorries and others overtaking me, but considering they have 2 lanes in which to pass me I feel no remorse Eco-driving the MSE way!

Are you an electric car driver?!
In the spirit of 'keeping the country moving' you might want to consider just driving at the same speed as the lorries, because they do have to make a lot of effort for an overtake. And it's not worth slipstreaming to save a few quid!

I just don't understand the drivers that don't seem to notice the road signs. E.g. speed limit increases to 40 or 50 but they carry on doing 30 on the dot. For some strange unknown reason they only notice speed cameras where they will slow down to 20 to pass them.

I use the A52 from Derby to Ashbourne five days a week.

Outside of Mackworth towards Kirk Langley it goes from a 30mph to a 50mph. Have lost count the amount of times people ahead of me have stuck to 30-35mph then decide to speed up as the road drops down to 40mph through Kirk Langley itself.

If the road conditions are good then 80% of the time I feel there's no excuse to drive dangerously slow. My pet hate is when people tailgate me and it's heavily raining!

What annoys me is people that describe people that do 45 in a 60 as dangerous. When in fact the dangerous one is them that sit too close then overtake close to bends and dips

Morning! :j

We are back to friction co-effecients, although wikipedia is not the best source, this page gives a good overview https://en.wikipedia.org/wiki/Friction

Back to your point....
If you have 2x identical cars, with identical tyres, identical axle weight, identical discs, pads, brake fluid & servos then there is no difference apart from driver ability (or lack thereof) or the friction surface (grass/tarmac/gravel). In theory they will stop at the same place and within the same amount of time.

However, change any of the variables above and you will see a difference (and in some instances a dramatic difference) in braking ability.

Discs/pads/tyre quality can vary by age of part, correct fitment, quality of part and materials used to produce the part.

As can brake fluid, in addition to brake fluid degrading over time and potentially becoming hydroscopic, lowering the boiling point redcucing braking effort.

I hope this helps, but it is the variables not the constants that will change the affect of braking and it's effeciency/use.

It's not as simple as thatiif your trying to justify tailgating. For it to be that simple both drivers would need to brake at thessame time - unlikely since the rear car has a restricted view.

So your largely relying on observing the car in fronts actions. And if your a second behind, chances are you've hit or about to hit him by time thinking time has converted to braking time.

My pet hate is cars that pass from behind me as soon as we hit one of the few straight patches in the road.

I'm sorry but my understanding of what you write above leads me to take some issue with this...

Why? What is it to you? If another driver is willing, ready and able to go for an overtake as soon as the opportunity presents itself - obviously an opportunity sizable enough for him to overtake the slow vehicle AND you - why does it affect you? Did you want to overtake too? If so, you've had more opportunity to commence your overtake than any driver behind you because you've exited the bend at least a car and gap length before them. If you wanted to go, I don't understand why you wouldn't have gone already? Your (perhaps hesitant?) driving style has obviously given the driver behind the impression that you're happy to proceed at the slower speed of the vehicle in front of you whereas he isn't (and also isn't hesitant) so has taken his opportunity to pass you both.

Also, you say you drive this road every day, yes? In that case you should know when the next straight will come and so ought to be ready for the overtake should the road ahead be clear enough.

All this means, as I see it, is that you're making your own bed by not taking your overtaking opportunities when they are handed to you which means you've got nothing to get resentful over.

Oh, and a couple of other things... as you're going through the bends don't sit on the back bumper of the slow vehicle, leave a comfortable gap. Use the gap to get your car set up and yourself ready (correct gear, visibility past the slow vehicle) and start picking up a little speed as you're exiting the bend so you're ready to go for the overtake if the straight is clear but also leave enough room to slow again and restart the process if it's not. And when you do take the opportunity to overtake NAIL IT(!!!) and get by as quickly as your little car will let you = "least time exposed to danger" and may give another driver behind you a chance to overtake the slow moving vehicle too on the same straight, i.e. also have some consideration for those behind who are trying to make some progress on their journey too. Having said that, don't leave a huge gap between the bends either or your position will possibly get "mugged" from you by a driver looking to jump the line. Finally, if someone does come past you or has to back out of an overtake ahead of you for goodness' sake DO NOT hang them out there. Not only is it petty and stupid, it is down right dangerous and could result in their death and even yours and others around you as no vehicle will just stop if it's hit. It is quite likely bounce off into yours or somebody else's vehicle. If the overtaking driver has got themselves into trouble, as a road user you are bound by a duty of care to do what you reasonably can to help them get themselves out of trouble and you could even be legally prosecuted as an accomplice to the incident.

My golden rule for my driving style is to make progress as I feel comfortable but have as little impact on other people's journeys as I can without disadvantaging myself, get out of people's way as soon as I can ...and certainly don't deliberately impede them. If they're not going to hold me up there's no reason for me to hold them up, and that goes for bikers too.
