Why keep 2 chevrons apart on motorways?

You could save paint by halving the number of chevrons and keep one
chevron apart.

You should keep two chevrons apart as if they get together they will
fight or mate, and you don't want that happening on the motorway.

I've never seen two chevrons together. They're usually miles apart,
interspersed with Shell, BP, Tesco, etc.

Funny was the intention, although if there was a sensible answer I'd

The sensible answer is that you don't keep two chevrons apart, you
keep one 'gap between chevrons' apart, and it takes two chevrons to
define the gap.

I don't think it's that simple. I suspect we are already expected to
interpret "please keep 2 chevrons apart" as "please keep 2 times the
gap between a pair of chevrons apart".

That is unless the motorway men wan't me to drive a whole lot closer
than the two second rule at 70 dictates - in which case they must be
fools.

If this is correct, which it might not be and I might just be over
cautious, "please keep 1 chevron" at least makes some sense.

It's probably meant to mean "please keep a distance between you and the
vehicle in front such that without modifying that distance, you can
always see at least two chevrons" but written by people who've never
had to write a software spec and are limited by sign space.

One chevron apart makes no sense, because they're only about a meter
from front to back.

I think your definition gives the same specified minium distance as
mine (at least in principle, since yours is defined in terms of what
the driver can actually see - because the driver's view of a chevron
immediately in front of his car is obscured by his bonnet, in practice
he will need to be slightly further away than twice the gap bewteen
chevrons with your definition).

I also stand my ground about one chevron - your definition would still
makes sense if the chevrons were twice as far apart and we were told
to keep one chevron apart - the "without modifying your distance" and
"always see at least one" means the driver will need to remain at
least the gap between a pair of chevrons apart to make sure he can
always see one.

christ, I'm dull.

If your car was see through and you were exactly on top of one, you
could see three chevrons for an instant, but normally you would only
see two....

But your diagram assumes that drivers will add on and extra amount of
half the distance between chevrons.  Why would anyone do this?  When I
drive such that I can see 2 chevrons, it's more like this:

-->----->----C>----->C----->----->---

Which means I see two chevrons every so often :-)

I think you're right that your diagram matches (at least every so
often!) the need to be two chevrons apart, and this is why the sign
wording is not clear as I think what the motorway enginerers really
want the distance to be is...

 -->----->----C>----->-----C>----->---

which a moment later will appear as in my original sketch with the
extra half gaps. Of course the real situation is

driving lane 1 = CCCCC>CCCCC>CCCCC>CCCCC>CCCCC>
                      -   -  M-   -   -   -   -   -   - M -   -   -
-   -   -   -
driving lane 2 = CCCCC>CCCCC>CCCCC>CCCCC>CCCCC>

where M = fast moving motorbike

We did this ages ago. I even did an ASCII diagram not unlike yours,

Two double-decker buses, four wardrobes and a washing machine.

Brilliant idea. I have so much trouble trying to spot the next chevron
and counting to two (or is it one?  When does the next "two" start?
After two, or with the one?) that  I often find myself up the arse of
the car in front before I've managed to work it out.

I think they should paint each section of the road red then green and
you shouldn't drive on the same colour road as the car in front

I admit my own interpretation of what was intended was wrong, I hadn't
seen the picture in the book and had thought it meant two gaps apart
not two chevrons, even though that is not what was said.

I think it should say "Drive no closer than the gap between a pair of
Chevrons, unless it's raining or icy weather in which case that will
probably be too close"

So how about a local sign now removed? "No Echelon Parking"
