The N chevrons away on those roads are often ludicrously far apart. It it well over the 2 second rule and nobody follows it.

There is no common 2 second rule, afaik. There is a 3 second rule, which is probably why they feel too far apart to you.

“Only a fool breaks the two second rule.”

It’s a UK thing:

My other pet peeve is the opposite - they've got LED daytime running lights, and use those instead of headlights. They're driving around at 11pm with no taillights and abysmal forward lighting, but there's enough of a glow from the DRLs that they assume their lights are on. Or worse, they're accustomed to "automatic" lights and don't even know where the switch is, so they're driving around at dusk or in fog, rain, or…

Or worse, they're accustomed to "automatic" lights and don't even know where the switch is, so they're driving around at dusk or in fog, rain, or snow in a white, gray, or black vehicle without their lights on.

The worst: automatic headlights required by regulations, but no corresponding automatic taillights. At least before those regulations one would notice the darkness in front and turn on (both) lights, but now you have drivers thinking their rear is also lit because the front is.

RE ".... get a mirror on my trunk that I can adjust the angle of from inside the cabin to reflect back high-beams at the driver. ...." I had this idea too this annoyance too - but never implemented it. One way to implement would be to mount a thin object , like a toothpick thickness and 1 or 2 cm long say on the mirror 90 degrees vertically to mirror surface , then (auto? ) adjust so their is no shadow from car's hea…

You don't need electronics for that, just corner-cube reflectors.

I understand that currently this is sort of a collective action problem, but I'm a bit baffled why people ever thought they needed brighter headlights in the first place. In the city, it's so bright that you don't even need headlights to see whatsoever. When cars started automatically dimming the dash via a light sensor, there was actually a period of time where I totally forgot to turn on my headlights because thing…

So who are they for?

Marketing.

Actual report appears to be this one, from January / February 2025:

https://www.trl.co.uk/Uploads/TRL/Documents/PPR2072---Glare-...

Finding participant / sample sizes for this is difficult, as it seems to be somewhere between a systematic review and a meta-analysis, but heavier on the recommendations than the analysis.

(I went looking because the 'nearly all' thing sounded like a bit of a stretch. Not that I would be surprised if this were true, but I would be surprised if they could make that claim with much confidence.)

I'm not here to debate the scientific evidence; labelling well-researched peer-reviewed studies as "paranoia" (your words, before editing your reply) because you don't like the outcome is absolutely your choice, and tells me there's little chance any reasoned reply will be meaningful as you've made up your mind.

How do you know? The vast majority of people don't check. (The plural of anecdote is not data.)

> As I said I've had to deal with someone that behaves exactly like you do for my entire life.

Baseless worry and justified concern are behaviourally quite similar, apart from the actual existence of the phenomenon that is the subject of concern. Identifying a behavioural similarity does not help you distinguish between legitimate risk and hypochondria.

If your front light is correctly aiming down, there’s no need to disable the light. Modern bicycle led front lights are most often incorrectly set up, though.

I can control the angle, but permanently aiming it down so far that it can't get in anyone's eyes is completely impractical. You would only see what's directly in front of you and you would miss a lot of stuff.

Not sure about your particular model but most front lights are designed to make the path visible in front of you, and not above.

if you ever visit Portland make one up reading YOU HAVE THE RIGHT OF WAY. drivers keep it weird here by ignoring the rules of the road for some kind of "no no i insist, after you" as if theyre giving some gift, but instead just confuse everyone if im biking and waiting at a stop sign: without fail, the last car in a long line of cars will slam on the breaks and insist i go when they have no stop sign. it would have b…

Defending that particular kind of driver: He might not have known to be the last car. But one thing he knows for sure: a long line of cars in front of him. Speeding up or keeping distance is pointless, so he uses that moment to be friendly instead.

i prefer predictability to friendliness every time

My 2017 Ford Fusion has an auto-dimming driver side mirror. I hate driving a car at night without this.

My rear view mirror does this, I wish my side mirrors did too. Although recently I've noticed some cars headlights can even pierce my rear view mirror's polarized dimming. It never used to be a problem in the past. I've seen the difference when drivers turn their high beams on and off. It always did a great job against driver's brights including large trucks. But occasionally there's now a vehicle with the light of a…

The older manual rear view mirrors worked much better in my opinion.
