Hi all,
First, I came up with that "hyper-illumination" theory, or least the
name. Perhaps. I will explain that in a moment.
For now I hope you will forgive the style in which I will try to
deconstruct a little what Lewis said a little earlier, using his text:

WHY have to think about it all?

I THINK if everyone focused on proper lights and reflectors - and bells
- it would solve half the problem. But also any promotion should be all
carrot, no stick.

THE European Cyclists Federation opposed this rule for the European
Union, because headlights obscure turn signals and tend to give drivers
the belief that they are safer

COMPLEMENTING measures to reduce the number of cars, lower their speeds
and make them softer on the outside. It would be best to make drivers
more vulnerable, too. Sure. How about airbags which turn off inside city
centers? (There is a famous joke about the safest car being one which
has a knife in the steering wheel pointing directly at the driver, but
also vehicles like this http://en.wikipedia.org/wiki/2CV are great for
vulnerable road users since their drivers are so vulnerable. Sure, their
emissions are a problem, so make them solar-powered and slow. Presto!)

HYPER-ILLUMINATION:
Hyper-illumination describes the concept of a cyclist or pedestrian
illuminating themselves as much as possible in order to get noticed and
be safer. For cyclists, this can be done with lights significantly
brighter than the required minimum, or with strobing or other unique
design features or reflective surfaces significantly higher than the
required minimum (including reflective vests or jackets and that
proposed "cyclist wing"). Since pedestrians do not (so far) have to wear
any illumination gear, hyper-illumination means anything more lit up
than wearing black clothing, unless for some reason black clothing is
not acceptable within a culture (never heard about this but simply
trying to make a point).
Things like a little bit of reflective tape on bike bags, running shoes,
children's shoes etc. are not hyper-illumination, but they are "assumed
visibility" (see below).
For both cyclists and pedestrians, this is indeed a selfish thing to do,
but specifically in two ways:
* Acutely: This means that at the time of cyclist/ped interaction with a
driver the hyper-illuminated cyclist or ped stands out BUT visually
drowns out other cyclists or peds very close by (further, depending on
the speed contrast between the cyclist/ped and the driver.
* Chronically: This means that in general if drivers start to get used
to cyclists or peds wearing being hyper-illuminated, they don't expect
cyclists or peds at other times and/or in other areas to not wear them,
so they don't look out for the latter, passively or subconsciously.
Reflective vests and jackets:
Reflective vests and jackets are made to reflect direct light, i.e. for
a cyclist or a pedestrian to be seen by a driver (in their headlamps).
If a bicycle has strong enough lights (laws generally talk about being
seen on a bike, not how much road surface a bike can illuminate) it may
make it possible for a cyclist to see a pedestrian.
However, they do not help cyclists get seen by pedestrians in cyclist -
ped interactions (unless the timing is right and a car travelling in the
opposite direction so that the vest or jacket is lit-up). A cyclist may
assume that they can be seen by the pedestrian at these or in general
but there is really no way of knowing!
At their worst, reflective vests and jackets "dangerize" a cyclist by
making their activity look dangerous, or - also for peds. - making them
look like security personnel, road workers, traffic police, etc and can
look really ugly and non-fashionable!
(A break for background: I have been through all of this, on both sides,
riding a bike with really bright lights, a reflective vest and so on....
and I also drove a 12 passenger airport shuttle van for some time)
Assumed visibility (or awareness)
This essentially means anytime two road users do not make eye contact,
or when a cyclist does not see body movement from a pedestrian ahead
which indicates that they have heard their bell (or similar, transposed
for cyclist/ped. - driver interactions). A driver is supposed to look
even after they signal when changing lanes, etc. , but at high speeds or
at night it is not possible to see the eyes or waving of the other
driver. Essentially this means that no vehicle shall be operated at
night if the operator is inside.... etc.
Cyclist Wing
I DO think the Cyclist Wing could be useful in specific actions, and the
cape idea mentioned already is nice because it implies a kind of heroism
(but runs the risk of getting self-righteous). The air will of course
not be cleaned in any measurable amount, and I think people already see
this stuff on their necks and shirt-collars, etc., right?
BACK to Hyper-Illumination:
This is really just a theory, but it feels right. As someone asked
earlier, it would be great to know if all this reflective stuff helps,
but my guess is that it does not. It would be great if anyone has the
resources for research, know who to ask for financial support orhas
influence over the right graduate students or their advisors, so that a
proper and thorough look into this can be made.
I am sorry I went on for so long BUT I hope this makes sense, and of
course I hope you all agree!
