I've never heard of such a case. I think it's yet another exaggerated
danger.

Bicycle lighting seems to be divided into "see where your going" and
"be seen" parts. Standlights are in the "be seen" part. If so, then
using a relatively narrow forward facing headlight is inadequate and a
poor substitute for all around "be seen" type lighting.

So far, no driver has tried to kill me while I'm stationary, but it's
possible. To help prevent such a threat, I would need all around
illumination because I don't know from what direction the driver might
approach and I do NOT need to see where I'm going (because I'm not
going anywhere). Some kind of flashing headband, flashing arm bands,
or maybe downward facing flood lights to illuminate an area. Maybe an
LED illuminated vest, which is now popular among highway workers:

I don't know which type of "be seen" lighting might be most effective,
but any of the aformentioned would be better than a dim forward facing
standlight.

Thing is, nobody's demonstrated any need for so much stationary "be
seen" light, beyond the usual "well, it _could_ happen" safety inflation
mentality.

We're facing the same mentality regarding our local forest preserve.
Some people want to cut down every dead or dying tree within 100 feet of
any trail because, well, it _could_ fall on somebody and kill them. Sheesh.

I have worked in area where it is probable that no one has ever cut
down a tree until we arrived and there never was a problem with dead
or diseased trees falling down.

One problem with cutting down trees that "could" fall down is that in
a hurricane many perfectly healthy trees get blown down. Perhaps the
cutting of all trees taller than the average human "could" lives.

And, of course, banning the ownership of bicycles "could" save ~900
lives a year.


A bicycle ban?
How's that 100-year worldwide Heroin ban working?
