Amber doesn't just mean stop, as if it did we would be the same as

There is a fairly good case for us doing just that these days. The red
and amber sequence had some merit in the days when everyone put the
vehicle in neutral and applied the handbrake when stopped at lights,
but it it is increasingly irrelevant to modern driving and removing it
could reduce accidents caused by drivers starting off before the green.

Do you mean that people are being taught nowadays *not* to put the car
into neutral and apply the handbrake whenever they are stationary? Or is
that just due to bad habits?

Maybe I'm old fashioned but I *always* put the car into neutral and
apply the handbrake when I'm stopped at lights or a junction, and I
never ever ever keep my foot on the footbrake because the brake lights
would dazzle the driver behind, especially at night.

And I certainly never try to hold the car on an uphill by slipping the
clutch while applying a bit of power - I've got too much sympathy for my
clutch plates, and I know that it's all too easy for your clutch foot to
move slightly after a long wait, which would either make you roll back
into the car behind or shoot forward into the car in front.

You obviously still drive a manual transmission car. Putting the car
into neutral is to reduce wear on the bearings that would result if
you simply keep the clutch down. Neither that nor 'slipping the
clutch' apply when driving an automatic.

It's also so you aren't at risk of catapulting forward if your foot
slips off the pedal after staying like this when waiting a long time at
a junction.

I've not come across that explanation before and I don't ever recall
waiting at a junction long enough for it to be likely.

I don't drive automatics much - I far prefer being in control of when
the gear change takes place (even though I accept that automatics can
achieve a smoother change than I can), because automatics tend to favour
low gear over higher gear and wider throttle when accelerating gently
out of a roundabout - and the unexpected change of gear after I've
selected the amount of throttle is most unwelcome! [2]

You need to try a better automatic car, or maybe one with better sound
insulation. I cannot tell when mine changes gear, nor would I expect to.
The engine is not audible and the pedal on the right only tells the
computer whether I want to go faster or not. It is up to the car how it
sorts that out for itself, although I can tell it whether to prioritise
economy or performance.

But when I've driven them, I've always put the selector into neutral and
applied the handbrake at a junction, exactly as for a manual,so as to
be able to remain stationary without my foot on the footbrake, blinding
the car behind with my brakelights. [1] It's only recently that I've
learned that shifting into neutral is not advised with automatic, though
I've never seen it actually documented in any user manual for a car.

There is no advantage to selecting neutral and, as it permits the car to
move under its own weight, it gives you less control. Selecting Park has
the same effect as selecting neutral and applying the parking brake, but
involves fewer actions to do and undo.

[1] As I was taught both for my normal and IAM tests: "footbrake to slow
the car down and bring to a stop; handbrake to *keep* it stopped;
*never* sit at lights with your foot on the footbrake".

Again, advice for a manual transmission. Park applies a transmission
brake that is as effective.

That was the
advice in 1980 and 1990 respectively. And I curse drivers in front of me
who don't do this, especially when shuttling forward in a long queue of
traffic and I start seeing spots before my eyes after a few minutes.

[2] I had a very bad experience in an auto Ford Focus hire car on a trip
from work, which decided that it wouldn't go faster than 50 mph: I could
have 50 in any of 4th, 3rd or 2nd gear depending on how much throttle I
gave it, but it was very reluctant to stay in top gear and let me go any
faster.

Sounds like a get you home mode had cut in after it detected a fault.
