I was at a junction the other day, there was some new Audi EV at the other side of the junction and I couldn't see a damn thing. I've got perfect 20/20 vision, never had any form of eye problem ever in my life, and I was completely blinded. I'm convinced if they'd turned the full beams on, I'd have disintegrated.

Part of the problem I've identified are SUV's and Trucks. Back home I drive a 4runner so I never noticed this but on vacation one week and we rented a Corolla. While the lights from other cars never bothered me in the 4runner, it was so apparent in the smaller Corolla.

I would see light behind me and go "why do they have high beams on" but then looking ahead it didn't look like they had their high beams on, I was just in a short car.

> but then looking ahead it didn't look like they had their high beams on, I was just in a short car.

You were in a normal car, and the SUV manufacturer has mounted the lights higher just for aesthetic reasons.

You were in a normal car ... for 2004.

Now you're in a car that the US car industry doesn't want to sell, and thus you don't exist.

Do we need self-darkening HUDs? Like an LCD overlay that specifically mutes the intensity of these improperly engineered cars? Seems dumb, but it might happen.

I wonder if we'll just move to using IR for the really high beams? That probably doesn't do anything good to the human eye at high intensities, but if you could augment the driver's vision and not blind everyone at the same time that would be nice? Let's bring back the Cadillac Deville!

Some high-end cars use banks of lights all pointing in slightly different directions, and they autodim the lights pointing directly at headlights coming the other way.

EDIT - also:

> Now you're in a car that the US car industry doesn't want to sell, and thus you don't exist.

To be fair, this is related to the cars people want to buy. Everyone's making SUVs because they sell like hot cakes.

Seems like it would make sense to mandate a specific height for headlamps. I wonder why this hasn’t been done.
Edit: sorry, I shouldn't post US rules on a UK topic. For penance, a fact about lighting in the UK, reverse lights weren't required until 2009!

There are rules. FMVSS [1] says lower beam headlamps must be mounted between 55.9 cm and 137.2 cm above the ground, and upper beam headlamps must be mounted not less than 22 inches nor more than 54 inches. The height ranges match, but are specified in different units

But that's a big range.

These rules end up being the stick used to regulate vehicle lifts and lowering; you could lift a vehicle higher, or drop it lower but very few people will do the work to relocate the lights.

[1] https://www.ecfr.gov/current/title-49/subtitle-B/chapter-V/p... Table 1-A, seach in page for 'Expand Table' cause I couldn't find a good way to navigate.

this is also my understanding. The range is large because it caters to passenger cars, lorries and construction equipment. Construction equipment is seen are more rugged (it often is) and this is now projected as a desirable trait for SUVs and pickup trucks.

The irony is that SUVs and pickup trucks do not need lights 137 cm above ground, but that height is perfectly legal in too many countries. These vehicles are a menace and should be legislated out of existence.

I will always champion the compact pickup truck. A 1980s S-10 or Toyota Truck (HiLux) can do light truck things, is relatively economical, and doesn't have a large footprint. Alas, nobody makes similar vehicles for US/Europe anymore --- kei trucks are still made for Japan, and less developed economies can get simple small trucks. Maybe some of the EV compact trucks will actually be made.
It's not necessarily height. Angle of the lamp impacts things as well.
Yeah I'm in a really low Civic Type-R, so when I'm opposite some kind of SUV, and also at a slight angle, was basically at direct eye height with their LEDs. I definitely don't have the same problem with older bulb based SUVs though
I do, because in my corner of the world, before the advent of self-leveling headlights people would adjust them to whatever height they wanted.
you weren't in a short car, you were in a normal car. Society really needs legislation around auto obesity. Cars are too big, too high, too heavy, all at despite being less practical than a station wagon from twenty years back.
Blame the obama CAFE regulations that accounted for wheelbase and car volume, giving manufacturers lower fuel economy standards for larger cars. Then the CAFE standards that hold trucks/SUVs to a lower standard.

The economically efficient way to get the fuel economy result would have been to increase gasoline taxes, but that's a non starter politically. Higher gas prices would allow people to choose to keep a cheap gas guzzling truck/car, buy a new more efficient and expensive car, or buy a new slightly more efficient slightly more expensive car. It would have been simpler though and given consumers more choice.

While drastically higher gas prices would have been the proper solution, the CAFE standards did not incentivize people to buy larger/taller vehicles.

People’s desire to sit higher up and be in large vehicles, which have always been more expensive than smaller, lower vehicles, is what causes them to be bought. And once a significant portion have them, it becomes safer to be in one yourself, further incentivizing their purchase.

But 99% of the time, it’s just because people like the feeling of sitting higher up than others, and the ego boost from taking up more space. The simple evidence is the popularity of Suburbans/Sequoias/XC90s/etc over minivans, like Sienna/Odyssey. There is absolutely no functional benefit of the former over the latter, yet the former is more popular.

Minivans really did suck in comparison to most SUVs. The vast majority of them were underpowered, had electrical problem, and their insides fell apart rather quickly.
I can't say I have experienced those issues between Odysseys and Siennas, but those are quality problems, nothing inherent to the concept of a minivan. I don't believe a minivan is or was underpowered for 99% of people's needs, especially to move family in a 1 hour radius.
i wonder if the incessant marketing from US auto companies had anything to do with this "desire". Why invest in more efficient engines, at lower profit margins, when you can convince your customers that their obese vehicles are all the protection they need.

There are very few countries where pedestrial fatalities have continued to rise, and the US and Canada are two of them, driven in large part by auto obesity.

You point to popularity, but I will mention that it is impossible to buy a sedan from US automakers today. The reason why is simple - profit. Larger cars are more profitable. When combined with incessant marketing that a pickup truck makes you more "manly", you can manufacture "desire" and "preference".

>but I will mention that it is impossible to buy a sedan from US automakers today

Toyota/Honda/Subaru/Mazda/Tesla/Volkswagen manufacture sedans made in the US, that you can buy today. Not sure why it would make a difference where it is made anyway.

If you wanted a lower priced sedan, you would choose from the 10+ great options, cheaper than a larger vehicle, and buy a sedan.

Which means if you paid more for a larger/higher vehicle, it is because you wanted the larger/higher vehicle.

Well either that or completely privatize the infrastructure needed to operate those cars like multi-lane roads and parking lots with no mandatory minimums for road width and parking lot size.
> you weren't in a short car, you were in a normal car

What's normal can change. Today, 37% of used registrations in the US are sedans and about 18% of new registrations.

yes, what is "normal" has been redefined to align with what is more profitable for the US auto companies. There is no real reason why most US drivers suddenly switched from sedans to large SUVs and bloody pickup trucks in the past 40 years. Except for profit.
Honestly the worst offenders for shooting the lights right in your eyes are the Jeep Wranglers. I drive a work truck on occasion and the Jeeps are about the only vehicle that still get me looking for the fog line. High intensity lights are still really annoying though, and my eyes are probably 7-8ft off the ground.
Wranglers are often lifted via the aftermarket, and I bet a lot of people who do that don't ever stop to consider whether the headlights need to be realigned after.
My experience has been all Wranglers unless they have aftermarket "eyelids". I think their stock lights have zero angle and just blast straight ahead without pointing towards the ground. Most high intensity lights tend to point at the ground so you don't usually get it straight into your eyes.
That's the worse for you driving a work truck. For people in shorter cars, the Wranglers might actually be above our sightlines, and the Dodge Ram tailgating us is among the worst.
I high-beamed one of them, then they turned their high beams on - it was a shockingly ridiculous amount of light that's simply dangerous anywhere. Fuck Audi.

Man, this feels like a vehicular instantiation of class war. Pay enough and you too can blind others on the road.

What's next - frickin laser beams?

There are definitely some brands that market "laser lights". Now, they're not really lasers, but still.

Well all the Uber/Lyft drivers have led light bars mounted on their Prius’ now so the class warfare is well underway I suppose.
One thought I've had with the matrix projectors on my Lightning is that it would be nice if they were able to dim parts of the beam that were below the normal threshold for low/high. It reliably turns off the bright parts above that line, but it seems like the "low beam" area is fixed. So on small hills and such I'll occasionally beam people directly in the face with a lot of light. Mostly that happens when the distance is still far enough that it won't be nearly as bad as when you're just across an intersection, but it's still fairly bright IMO.

I assume regulation prevents the dynamic lighting from including the low beam section.

Maybe they were on a slight up slope. If the headlights were auto leveling it will fix many of the issues people complain about.
Yeah quite possibly actually, I did think at the time if they were angled down slightly, it wouldn't be half as bad. So that checks out. But does show there needs to be some kind of solution for uneven situations like that
