Consider your average 2-lane road (2 lanes in each
direction). The width of each lane is pretty much an
International Standard (ignoring modest variations),
because cars are sold all over the world, and drivers expect
their cars to fit on the lanes.
We note that in most places the color "white"
is used for
painting various stripes on the roadway, to indicate to
drivers the limits of the lanes.
Nowadays, mostly due to fuel prices, a lot of smaller-sized
cars are being sold. They are smaller both in length and in
width --some of them are enough narrower that you could
probably fit 3 of them side-by side on a 2-lane road, and
still have a safe distance between them.
Paint additional lane-stripes on the road, in a different
color (perhaps that glaring "yellow-green" color). If you are
driving an ordinary car, use the white lines as normal. If
you are driving a narrow car, use the new lane lines,
mostly the left or right lines, not the middle lane.
Use the middle lane ONLY when the cars to the left and
right are also narrow cars.
The net effect is that more cars overall can fit in a given
"length" of rush-hour traffic (EVEN more when you include
the fact that the narrow cars are also shorter).
This Idea could encourage greater sales of narrower cars,
simply because their drivers can feel special, because the
special lanes would exist. And the more narrow cars on
the road, the more often that middle lane can have a car
Overall, we have a positive feed-back loop that encourages
less material resources be used on each car, less energy be
used to move each car, and so on.

||I beg to differ, Sir Vernon. Ever been to Yorkshire? I almost
lost a mirror to an oncoming Vauxhall Astra on a B-road,
which apparently is considered quite roomy by English
standards. I'd hate to think what a massacre it might have
been if I wasn't on a motorcycle.
||[Alterother], perhaps you missed the parenthetical (2
lanes in each direction)? So far as I know, places that
actually have 4 lanes total, for bi-directional traffic,
are using lane-widths that resemble an International
||Perhaps it's the standard in some nations and not others.
The motorways and A-roads in England certainly share the
generous dimensions of most North American roadways, but
large thoroughfares in Italy, for instance, seem built to
some insane Lilliputian standard. The Swiss think it's
perfectly acceptable to drive semi trucks down lanes no
wider than my upstairs hallway, and my Uncle Mike claims
there are no roads in rural Hungary capable of
accomodating a Toyota Hilux, not that it stops the
Hungarians trying to pass each other on blind curves as a
matter of common practice. Maybe this standard lane
width only applies in built-up areas.
||Anyway, with so many companies branching into microcars
and advanced hybrids (which, ironically, use more
petrochemicals, rare-earth metals, and vile pollutants in
construction than their lowered 'carbon footprint' could
compensate for in a hundred years), it hardly seems
necessary to further encourage the trend by wasting paint.
||Cairo during rush hour is this idea minus the lines:
the cars are on the small side and pack six abreast on
a nominally four-lane road.
||There is a thing in railways called a gauntlet track
[link]. It's insane. This is slightly less insane. But it
takes for granted that motorists are rational and
cooperative so [+] for optimism.
||the idea that // smaller-sized cars are being sold// is
false. Cars have grown, pretty dramatically, due to
safety standards. The best evidence, is something
like a VW golf, small by US standards but look at Mk1
Vs 2,3,4,5 etc. The new Mini, for example has a
bigger footprint than the original Land Rover.
||Canada tends to use yellow lines to delineate the boundary
between oncoming traffic (yellow also shows up better
when there's a bit of snow or frost around) and use white
lines to delineate lanes going in the same direction.
||The problem with this posting is that it requires common
sense and judgement from the drivers as to whether or not
their car and others nearby are narrow 'enough' to go 3
abreast. That's just asking for trouble.
||// (which, ironically, use more petrochemicals,
rare-earth metals, and vile pollutants in

||Please cite a source. The only paper I've seen
that actually suggested that was a deliberate hit
piece, and gave the credit for every bit of
pollution from several rather old mines exclusively
cars. Most impartial studies suggest that the
cradle to grave resource consumption of a Toyota
Prius is comparable to similarly sized cars if no
extraordinary recycling programs are used
(meaning only steel and such that is typically
recycled), and potentially much better if decent
recycling programs are used.
||This tips further in favor of the hybrid if both
vehicles are built in "zero-landfill" plants, which
are becoming more and more common.

||Try North Wales, or Cornwall, or the North-West of Scotland.
||Admittedly in North Wales the main hazard tends to be sheep doing a runner from their pimps. Cornwall bears a striking resemblance tor the Bocage country of Normandy, about which much has been written*. North-West Scotland simply suffers from a lack of anything resembling civilization; roads, houses, cooking food, not living in trees, a spoken languagem or the use of fire. But they do seem to have grasped very firmly the concept of edged weapons, as clearly as they grasp the weapons themselves.The Romans, having visited briefly, built a wall; it's easy to see why.
||* Welding large steel wedges to the front of an M4 Sherman tank is highly recommended. Make sure you have the Firefly version, up-gunned to carry the British 17-pdr antitank gun, otherwise you may find parking in Rouen a bit of a trial; the .30cal Browning on the turret is handy for explaining that no, you do not want to pay for having your windscreen washed as an alternative to having your aerial snapped off.
