It's a long time since anyone added to this topic!
Looking at .13, one has to remember that the thinking and braking
times in the Highway Code were "dreamed up" at about the time when four
wheel brakes (on cars, not motorbikes! 8^)) were a fairly new thing on
ALL cars and the figures have never been updated.
Most cars today can approach and a few can even exceed 1g of braking
on a dry road with todays brakes/tyres/Road surfaces. This makes a
mockery of the Highway code braking section figures!
The thinking time part of the figures relates to a reaction time of
about .7 second which is pretty slow!
I still recon the 2 second rule is emminently sensible though as a
general guide.
Regarding the M25, using the 2 second rule, this limits the maximum
throughput at 5,400 vehicles per hour. Since the traffic trying to use
this road is well in excess of this during large parts of the "normal"
day, is it any wonder that it is now refered to as "the worlds largest
car park!"
Anybody want to comment about these?

Malcolm,
not wishing to be pedantic :-) (but why change a habit of a
lifetime)... the braking distances in the highway code are "safe
braking" distances. Different people see this differently. My idea of
safe is "with little or no stress/effect to either driver or
passengers".
To practise safe braking technique place/stick 1x1 pint container to
dashboard of vehicle. Place into container .75 pint of H�0+* (tap
water) now drive smoothly so as not to spill ANY water, during
accelerating, stoping, deviating course etc.
Alan.
ps the Highway code "braking distances" have not been changed because
the mesurement for their calculation has not changed (as above).

241.43 | ABS or not ABS - that is the question! | RUTILE::BISHOP | What the HELL are you talking about man! | Fri Sep 04 1992 16:02 | 25 |
| Well, i'm not too sure what can be counted as a safe distance in
measure nowdays... as far away as possible i would have thought!
On a recent trip to Munich, driving along at about 90-95mph on a
Swiss autoroute there was suddenly a traffic-jam! 2 cars infront of
us (we were in an Espace) SLAMMED on their brakes, i done likewise
and the person behind me had to swerve towards the central reservation
so that the car behind him would stop OK.
In this situation, i don't know if i was 2 seconds between cars,
and i don't really care, but it sure as hell was toooo close anyway.
It definativly made me nervous for the rest of the trip!
I always find these kind of arguments mildly amusing... a friend
here always leaves his braking till REAL late... when questioned he
replies "Yea, i've got ABS"... he doesn't seem to realise that the
poor bugger behind him may not!
Until ALL cars have the same standard of brakes etc i don't think
anyone can generalize this rule... after all, isn't it better to teach
our younger drivers this? Because it's always better to be safer than
sorry.

| The one thing to remember about ABS is that all it does is turn your
brakes OFF.
Should it go wrong.......

Failure state of ABS is off, so the brakes will simply lock up.
Allegedly!
Funny about the comment about people behind not having ABS. This
assumes that the person behind waits for the one in front to brake
(or at least uses that information as a guide). Some will argue that
using your brakes at all is a last resort, but I agree that braking
helps other road users to be aware of what's going on ahead.

241.46 | whilst we're on t'subject | DUBSWS::KANE_BF | The clot thickens.... | Fri Sep 04 1992 18:15 | 6 |
| The highway code states (and I'm paraphrasing here so no pedantry please)
that it takes a car 90 yards to stop from 60mph.
A Porche 911 Turbo does it in 90..

| I was surprised at the one month prison sentence that a 21 year old
single mother got for giving a false name and address when stopped
by police for not having road tax.
Whilst this was of course totally wrong, does the punishment fit the
crime ? Especially when you consider the ridiculous punishment of a few
hours community service that some of the louts on the Police STOP!
video received for endangering their own lives, and the lives of the
police and general public.

| What authority do 'Transport Police' have. I always thought they were
British Rail security rather than an arm of the police force. If so
what gives them the right to drive round in marked transport police
cars with blue lights ?
Just curious.

| It is my understanding that they are a police force like any other but
they have "British Rail" as their beat rather than Manchester or other
town/city.
There is also the Atomic Energy Police who carry arms and guard nuclear
establishments.
I wonder what happens to the Transport Police in Rail privatisation?

| Wot .50 said.
I had a long chat with these chaps when my wife's car was knicked from
a BR station. They actually (IMHO) do a better job, as (presumably) BT
enforce different rules on them. For car theft, they actually do
something, they fingerprinted the car when it was found, for example!

| I'm still confused. Andrew mentioned that they are like any other
police force but I thought there was only one official police force in
the UK. Arn't the transport police more of a security group ?
The point I'm trying to make is what right do they have to use blue
lights on a marked up 'police' car. Could Digital set up a 'Viables Car
Park Police Force' with suitably uniformed 'policemen' in a marked car
etc. ?

241.53 | | CHEFS::FIDDLER_M | The sense of being dulls my mind | Tue Mar 05 1996 11:50 | 6 |
| I think they are an 'official' police force - there is a Trivial
Pursuits question which is something like 'what is the only national
police force in the UK?', or somesuch, the answer to which is the BR
Transport police.

| Well maybe there is only one police force - split into many parts eg
Metropolitan, North Yorkshire etc. I believe that the Transport Police
are on a par with these other "divisions". They are not on a par with
Group 4, Securicor.
The British Transport Police have powers of arrest etc like any other
police force, they just specialise in transport related crime.

| If that's the case Andrew that clears up my confusion. I just thought
that the Transport Police was an arm of BR rather than The Police
Force.

| No, I think the county (and presumable metropolitain area) police
forces really are separate forces, not divisions of the same force.

| -.1 is correct, there is NO national police force. For most of
the UK the County Council is also the local Police Authority,
although some Counties share an authority (e.g. Devon & Cornwall).
