Well, two questions...
1) You seem to be sodding brilliant at answering questions, so who are you? (Probability of answering question: 2%)
2) Accleration Sense: You have already answered my question about overtaking on left handers on d/cs - when driving as fast as you possibly can, does acceleration sense go out of the window? As far as I can see the easiest way (if you couldn't give a damn about the brakes) to get anywhere is to use the brakes... You could, however, go faster using the brakes. "No one"* knows who you are, but if speed as of the utmost importance what you be doing?
*I have a pretty good idea, but despite my _deservedly_ retarded online nature I do know people on every side of the fence
Footnote: Before, when being followed by unmarked police, I have used the handbrake, purely to convince the police that I have even better anticipation than I have (when people in front have braked unexpectantly); is this really stupid?

I've answered that already. I'm a Police officer & driving instructor.

No matter how fast I am travelling I try to use acceleration sense as my first method of speed loss, (it's the smoothest way to lose speed) followed by gentle brakes. The transition between the two should be so smooth that the change point should be imperceptible to passengers (ie they know we weren't braking & that we now are but they can't tell when that exactly changed). From that starting point we can progressively squeeze to firmer brakes as required smoothly moving the weight in the car.
In order to be able to do it well you are going to have to make time for it in your drive & plan it's use. If you merely react to what you see you won't be able to.
Whether I brake for a bend or not depends on how much speed I have to lose, on open bends where I don't have to lose large amounts without sacrificing progress, I'll do it on acceleration sense only, on tight bends where I have been carrying a lot of speed I'll make progress to it & lose the speed with the use of firmer brakes before entry (still must go through acceleration sense, 1st & 2nd stages though)

If they are switched on they'll know what you are doing & if you aren't you may end up giving a drift exhibition.
I think it better to work on your anticipation rather than to try & con yourself or others that you have more than you have.

Can anyone translate that for me?
Using the handbrake to scrub off speed while at speed is not a good idea, especially if it's a dedicated parking brake.
Using the handbrake to lose speed without lighting up the brakelights, thus appearing as if you anticipated the car in front slowing a long while back. NOT using it as a binary option, and locking up...

This can only lead to a loss of rear end stability surely?
Rear wheel braking as created by handbrake usage isnt my idea of a particularly safe braking method, id go so far as to say its foolish to use it in this manner as A)its not intended for the purpose of slowing a moving vehicle, and B) If the road surface is lacking in traction youll end up doing a very fast spin indeed if you get it wrong.
Those that use acceleration sense - the ability to vary the speed of a vehicle when braking is not demanded - invariably beacuse of their anticipation skills also 'feather' the brakes if required - i.e. very light application.
Was always told this tends to shine the discs to the detriment of harder braking should it be demanded.
The cure - now and again put them on hard where safe to get rid of the shine.

What's all this talk about acceleration sense? Is it what used to be called "the overrun" (i.e. engine braking, but not dropping a cog).
It's just a term given to the sort of subtle forward planning leading to (often subtle) speed adjustment that leaves you arriving at hazards at the right speed and at the right time without apparent effort.
I reckon it's a good term for one of the slightly finer driving 'arts'.

Or is it some Jedi mind-trick that I don't know?

When you first encounter it the term does seem misleading. Perhaps quite often it could better be known as decelleration sense.
I may be wrong but I take it to cover most use of the throttle pedal, e.g. avoiding too much sustained throttle at a time when you are very soon going to have to lose speed on the approach to a hazard.
A young fellow in Scarborough gave a good example of this a while back. He pulled away from the side of the road, accelerated very hard for about two seconds, then immediately braked hard to a stop at the tail end of a traffic queue which had been there all the time! Still, I probably did the same sort of thing 40 years ago!
Best wishes all,
Dave.
Ah, now I know what you mean. I know it by a different name though; I call it "driving", it's an alternative to "holding a license under false pretences"!
I've always driven in that manner, as it's the way in which I was taught by my father, who also taught my brother and so I just assumed it's the way everyone drove. In fact, come to think of it I rarely use the brakes (or at least, more that an subtle hint that I don't even realise I'm applying), only for pulling up to junctions.

Your driving would be a mixture anyway.
Open bends, only smaller speed loss required = acceleration sense only
Tight bends = make progress to them, followed by some acceleration sense & 3 stages of braking.
Positive junctions (T junctions, roundabouts) = make progress to them, followed by acceleration sense & 3 stages of braking.

Sure, but you also use it when accelerating (e.g. if the queue of traffic had been moving at around 15 mph, you'd use acceleration sense to get to around 20 to catch up and then use acceeleration sense to decellerate to the 15.)

You squeeze the throttle exiting hazard "A" by exactly the right amount & then come off the throttle at exactly the right time so that you approach hazard "B" at the correct speed to negotiate it without any braking.
Too short & you have to pick up the throttle early because you've under done it. Too far & you'll have to brake because you've over done it.

Yes I know that, and I find it generally works out quite well, but the young guy I was mentioning was accelerating hard (albeit briefly) towards the tail end of a queue that was stationary all the time and only a short distance ahead of him.
Best wishes all,
Dave.

If you have time to try and work out that you didn't want the unmarked police behind to figure out that you hadn't anticipated a traffic problem ahead.... and then use the handbrake to kid them.... surely you'd have been better off just taking your foot off the go pedal as soon as you considered starting this bizzare chain of thoughts?
or would that be too simple?
