Over here I don't think I've ever seeing anyone with a white
front light but red "tail lights" seem to have become the
norm.

But I do believe that anything that makes the bicyclist more
noticeable would be a good thing.

Yes, I've noticed more DRLs. For one thing, every e-bike I
encounter seems to be running with its headlight on. But I
see a few roadies running daytime headlights, and more of
them running taillights.

But I disagree with John's final sentence. A guy running a
headlight when out on a lonely country road in bright
daylight? That's a "good thing" only for the companies
involved in the light sale. It does no real good for the
cyclist.

You missed the part about "makes the bicyclist more noticeable
would be a good thing"? Obviously if the cyclist is "more
noticeable" there must be those who would notice him/her/it.

Noticing a cyclist who is two blocks away confers no benefit.

Well, "two blocks" is covered pretty darn quickly at highway
speeds, so perhaps there is some benefit in being seen at greater
distance.

If the cyclist is two blocks (say, 1000 ft) away and moving just 12 mph
in the same direction as a 55 mph car, it takes over 15 seconds for the
car to reach the cyclist. 15 seconds is quite a long time in driving.
Count it out to visualize it.

But, but...The discussion was about a white light on the front of a
bicycle so your figures are not correct, it is actually closer to 10
seconds and for someone talking, reading a message or texting, on a
phone that isn't a very long time. And... some 26% of traffic
accidents are a result of hand phone use while driving.
Better double check your math, John. 1000 ft divided by 43 miles per
hour (= closing speed) times 3600 seconds per hour divided by 5280 feet
per mile.

There’s still a 3.6 conversion factor if you do it in metric.

????????? I don't live in Russia, but I still think Putin is a horrible dictator. I don't live in Turkey, but I still think Erdogan is not a good person. And there are lots of other countries I don't live in but I still think the country leader is bad. Under your very bad logic, the USA should never ever have entered WW2 against the Germans because Germany never directly attacked the USA.

France did try to implement decimal time, shortly after the revolution.
For some reason it never took off, and we've been stuck on base 60 since
Sumer was a leading capital.

If they proposed it today I would be in favor. Rode 86 km in 2hr45min36sec. Average speed on my RPN calculator:
2 enter 45 enter 60 / + 36 enter 60 / 60 /+ 1/x 86 * tada 31.16 km/hr..... pfff.
It could have been 86 enter 2.76 /

How so 43 mph? As I mentioned the discussion was about a white light
on the FRONT of the bike so, logically, it would only be effective
when the bike was headed TOWARD something. Your argument seems to be
that a FRONT light would be visible to vehicles behind the bicycle.
