[NA] 614 trillion lumen headlights

OK . . . so manufacturers came up with better headlights to match speeds. So now we can drive 80-85mph and not outdrive the headlights. No national 55mph speed limit any more, so the headlight tech has adapted.

If these are for being able to drive at 80mph (which is illegal in most places) then what's keeping them from going further, then, and modulating the brightness based on the current ground speed?

Illegal? TX and OK have multiple highways/turnpikes with those speeds. However, as to your question I'm sure they could certainly get to that point, but the adaptive headlights currently in use in Europe and other countries essentially do the same thing by using sensors to detect oncoming cars and reduce output in that spot until the object has cleared.

"Most places"
But yes, there are a number of safety standards in place in the EU that we have not adopted. Some of these are among the many reasons why our roads are a bit deadlier per hour traveled than most other industrialized nations.
 
Seems easy (if adaptive lights are a bridge too far) to have low medium and high instead of just two

People can't manage high vs low right now, lol. My wife's Caddy with the auto-high beams can be a bit annoying when it picks up street lights and whatnot that cause it to turn off high beams erroneously.

Aren't there a number of cars that fix this, not with brightness, but by leading the lights into a turn? For instance, in my friend's X5 when he goes into a turn the lights point toward where he's beginning to go so your path is plenty lit. That seems like a better solution than an omnidirectional increase in brightness? At least I would think...

As a Hyundai sedan driver neither adaptive lights, fancy leading lights, or a ridiculous lift kit to get higher up/out of the way of truck/suv lights are in the realm of possibility. So if I want more brightness the best I can achieve is holding a maglite flashlight out my window and pointing it to where I intend to look. But that ghetto approach would look like poverty on wheels, so I'm relegated to just using my pleb headlights + brights for now and suffering through the ridiculous lights of others :)
 
Also, this brief clip about from the muppets movie is probably the best analogy to how it feels to face that **** in oncoming traffic

 
OK doesn't do inspections of any sort, so no luck there, lol. Pretty sure TX got rid of most of theirs, too.
TX just eliminated state-mandated veh inspections, though individual counties can still levy their own requirements.

But even when state-mandated inspections were still required, headlight aiming was not part of the test...they just had to come on and be "white-ish". :rolleyes:

Even in a straight line, the faster your speed, the more room you need to either stop or take evasive action safely, so the farther your lights need to illuminate the road in front of you to avoid "outdriving the headlights".

Driving around curves just makes that harder. Angling the headlights into a curve can help with with that problem, but only after your headlights are already illuminating enough of the road to be appropriate for the speed you're driving.

Huh, interesting... I guess I personally have never had an issue driving 80mph on a straight away with things not being lit enough.
When things are that dark it's usually cuz there are no cars around and I'm clear to turn on my brights. But that's just my experience.

Yes: There are reasons why there's not a nightly catastrophe of cars speeding into collisions on the highways. For the most part, headlights provide adequate illumination. Also, it's relatively uncommon for hard-to-see obstacles to suddenly appear on highways. Thus, most people have never had an issue with driving at highway speeds on straight roads.

But that just means the problem has mostly been solved, and that those cars that don't solve it are mostly lucky, rather than "there is no problem".

My wife's caddy has headlights that follow the steering wheel as you turn which is a great feature. The difference with adaptive headlights in Europe is that the lights have active shutters/diodes that can quickly blank out the light from shining on an oncoming vehicle. It doesn't reduce brightness, it just essentially blocks the light from being directed into the driver's area, then unblocks it when the vehicle has passed. It's cool tech, but as mentioned previously it's been held back by NHTSA in the US for god knows what reason.

I don’t own a car so I only drive the occasional courtesy car or rental.

I often find that the headlights are poorly aimed; mostly down to reduce the distance you can see. I think this is to force drivers to drive slower.
 
Vehicles have also gotten taller. Unless you’re also in a truck or SUV headlights from other vehicles are much closer, if not above, eye level.
I drive a 2008 rav4, not exactly a tiny, low to the ground sports car. The amount I get blinded by people driving in their overcompensation-mobiles is insane. Their headlights are basically at my eye level.
