Over-powerful LED lights

What's best for the person who the manufacturers are designing the car for: the driver who's buying it

But, as this thread, all the moaning that has prompted a government investigation into the topic, and multiple other bits of evidence suggest, they aren’t best for the driver who is buying it, because the driver who is buying it gets poked in the eyes by the lamps on all the other similar cars that other drivers have bought. The vast majority of the complaints about this come from drivers of cars.

You clearly don't understand what a Prisoner's Dilemma is, or how it arises. Driver's aren't going to make themselves better off by buying a car with dim lights regardless of what others do.

Thanks.

I found this FAQ shone a lot of light on the situation, without dazzing drowning me with data.

TRL seem a sensible bunch

Q24: Are cyclists and pedestrians just as vulnerable?
A: They could be - although they are often higher in the scene meaning headlamp
beams may not shine in their eye level as much.

This assumes that all pedestrians, and all cyclists, are adults.

"Back from the brink: UK red kites aid Spanish cousins"

Interesting dazzle characteristics from a following car yesterday. I was heading down the M6/M61 (our walking group had been on a walk starting/finishing near Glasson Dock & we were going back to Bolton).

There was a car behind us for quite a few miles with DRLs (I think) on. They stuck doggedly to the middle lane not really catching up with us. When I was in the same lane the lights were OK. But when I was back in the nearside lane, having overtaken something slower, both front lights were really dazzling (enough to make me dip the rearview mirror in broad daylight!). I don't know if it was by (bad) design or a fault & I didn't get to see if the same effect was there if I went out into the outside lane. The car turned out to be a VW id4 when it eventually passed after probably 10 to 15 minutes, but only because I had slowed down a bit.

That's interesting. If it's similar to our ID.3 it has very fancy headlights, which swivel to point in the direction the car is steering, and which, on auto main beam, detect the direction of nearby vehicles and turn off just the part of the beam pointing in that direction. It's impressive, actually the most interesting feature of the car, but I doubt it's completely foolproof.

You know the expression "high as a kite"?

On Jeremy Vine, R2, now.

I see quite a few younger motorcyclists and cyclists riding with dazzling lights by day and, codger that I am, occasionally have a word. They usually tell me it's to be noticed and I describe how with their background washed out there's no frame of reference: something's there alright but apparently not moving. The thing is I'm told my night vision's above average.

I've just discovered that some cars now have laser headlights, which are reportedly four times brighter than LEDs.

Most motorcycles nowadays have always-on headlights linked to the ignition switch. Been that way for at least a decade.

I doubt they'd get through the MOT or TA without a non-dazzling setting, it's more about how they (or DRLs) are used. Some of the cyclists said they had felt safer by dazzling intentionally.

I guess that's working of the principle that pissed off people know you are there. It has its virtues in some respects. Same as riding in the primary position I guess.

Real downside of things like that is they don't scale. The odd person micturating you off will be accommodated with slightly annoyed care, lots of folk doing it I don't think would work the same.

I prefer to work from the "treat others as you want to be treated", so as a driver that's not scaring people and as a rider not aiming blinding strobes at drivers' eyes
