They probably are fairly crude. I know they flicker, for
example
if
I
use my cordless drill, the chuck appears to spin the wrong
way
under
the
LED lighting.
I remember seeing that with a washing machine (under
fluorescent
lights). As the tub was slowing down, the row of holes around
the
tub
would appear to reverse direction. Same thing with (spoked)
wagon
wheels
in movies.

You can also observe such things using a smartphone that has a
high
FPS
rate for recodring movie.
I can see the labs lights flicker when I film at 240FPS
standard
60
and everything seems fine.

Everybody seems to constantly cut corners. Lights should just
be
on,
no
flicker at all. ****ing annoying if you have decent eyesight, I
can
see
the flicker from almost everyone's LED tail lights.


This is sounding more and more like our "engineer friend" who
needs
to do his own tire repairs and alignments and clutch repairs.

Don't know who you're referring to, but what's wrong with striving
for
perfection?

It increases costs for everyone who isnt a freak.

There's perfection and there's perfection. You for example like
LEDs
you
can control the colour of, nothing wrong with that. But OCD folk
take
things too far, like washing their car every day because of two
specks
of
dust.

All irrelevant to whether it makes any sense to design
all car lights so that no freak ever sees any flicker at all.

When "freak" is half the population,

Half the population don't see car lights flicker.

Agreed, and the other half do.

Bull**** they do.

you need to account for them.

Nope.

If you think they're a minority,

I know there are.

why does google have 4.5 million results for the car light flicker?

Just a few mindlessly ranting freaks, like you.

I must have asked about 30 people I know about it, and about half agreed
it was irritating.

The technical term for that is 'pathetically inadequate sample'

I've done statistics at uni,

And clearly the whole lot went right over your head, as always.

I know what an adequate sample is.

You clearly don't with that steaming turd above.

If half could actually see car lights flicker, the
designers wouldn't have designed them like that.

In spades with movies in movie theaters. That frame
rate was chosen because most couldn't see that flicker.
