When I lived in Canada we had to turn on the honk mode because there were too many people using devices that block remote vehicle locking. The honk is an obvious indicator that the car did, indeed, lock.

> there were too many people using devices that block remote vehicle locking I'd be interested in more context on that.

Here's for example an article in the Guardian from 2015: https://www.theguardian.com/technology/2015/may/26/high-tech...

shows basic lack of concern for other people's lives on the road, same as drunk driving. > because they used bright lights. Why are people doing this in the first place. I don't understand.

what does jailing someone achieve here? what is with this gross authoritarianism? most of these people using these bright LEDs dont realize how bright it is for the other drivers - it's probably just to make the roads brighter because driving in America is extremely different than the rest of the world (very very rural highways - with essentially no extra lighting)

> most of these people using these bright LEDs dont realize how bright it is for the other drivers

How can you possibly not know that. You are literally making them bighter so it would obviously be brighter for the drivers too. why do you think its illegal in the first place.

re: "aftermarket xenon bulb setups" Is this still a big problem? While I would have agreed with you, say, back in the 2000s when the whole "import tuner" craze was in full swing, I don't think this is popular anymore. The car mod scene seems to be close to extinct now, with whats left being a lot less crazy than those in the past.

You will see them far more often on large trucks in the USA these days. Especially true for midwest drives across long stretches at night where the brightness is much more annoying than in the middle of a city. If the truck is lifted, the brightest points of the light can hit you from further away, worsening the problem. It is also bad when someone is behind you with this setup, especially lifted trucks. Some cars ha…

> Some cars have a rear mirror that can dim them to tolerable levels, but not the side mirrors

The US National Highway Transportation Safety Administration actually has a suggestion for eliminating the glare and reducing blindspots [1]

I would say there is almost certainly a little wheel somewhere on your dashboard to adjust them. My Land Rover has this.

Not if they are halogens. I've only seen manual adjustment on HID-equipped cars, and only older ones. Most anything modern is auto-leveling.

It's bog-standard on my old Land Rover with weak yellow halogens. I think you'd find it hard to drive with a load in the back without them!

Even more importantly: Why is America still stuck with cars that honk when they're locked and that have indicator lights flashing in the same color as the tail-lights? One is a nuisance, the other one a straight-up safety issue.

When I lived in Canada we had to turn on the honk mode because there were too many people using devices that block remote vehicle locking. The honk is an obvious indicator that the car did, indeed, lock.

The range of the key should be tiny, so it should be easy to see the lights flash even in daylight (and often rearview mirrors fold).

If it can detect cars and de-illuminate, it shouldn't be too hard to detect and spot-light other things for safety, like people, animals, debris.

Current resolution generally seems to be less than 100 headlight 'pixels' so we may need more resolution before we can dim someone's face specifically.

But that could get especially interesting when you connect it to a self driving system. The car's AI could become a more active participant in 'looking' at things.

I really hate led headlights here in USA, They are too bright and need to be banned. People using these should be jailed for endangering lives. I don't know why but This seems to be particularly common here on big pickup trucks, which is even worse because they hit you right in your eyes if you are driving a regular car due to height difference. Also, I've had adaptive headlights on my subaru forever.

Maximum permissible wattage in USA headlights used to be 55 watts each (and probably still is). I don’t think there was ever a limit defined in lumens, so now we get LED lights with crazy brightness since they still use under 55 watts.

If the regulation isn't "55 Watts or equivalent brightness to 55W incandescent" then the regulation is pretty dumb. I mean it has to have a minimum brightness (regardless of power use), so why not a maximum brightness rather than a maximum power too?

groups like Audi/Porsche/BMW have trouble bringing their fancy LED setups to America due to laws pertaining to high / low beams -- meanwhile every Jack and Jill on the road has glaringly illegal aftermarket Xenon bulb setups in refractor headlight housings rather than proper projectors, blinding the hell out of everyone on the road, and the police seem to do nothing about it. I mean, hey -- i'm usually happy about au…

The worst thing to happen to America was Autozone and Fast and Furious. Cheap aftermarket modifications to your car being sold to people with no knowledge of what they were doing but wanted it too look cool cause they saw it in the movie. Its led to years of teenagers with no training putting things on their cars that turn them into obnoxious spectacles on the road. I know I sound like an old coot but frankly I'm gla…

> I know I sound like an old coot but frankly I'm glad my dad showed me how to install/aim headlights and along with explaining the benefits of a working unmodified exhaust system and how it should sound.

Reminds me of the hotrodding chapter of John Muirs[0] venerable How To Keep Your Volkswagen Alive [...] for the Compleat Idiot[1] that starts describing the interplay between various systems and how just throwing a hot cam into an engine and calling it a day is a bad idea. Basically - How to hotrod your engine:

1) don’t

2) if you must here’s what you really need to know

I think it's great that it's relatively common to work on a complex piece of machinery that you use daily. You get the joys of understanding how a large system works and being able to tweak it according to your desires. It could easily go the other way, where every subsystem is DRM'd and only licensed professionals were allowed to touch it.

Letting anyone do whatever they want can obviously lead to problems, like headlights that blind people or parts that fall off and kill the person behind them. But overall, I think I like the world where people are free to experiment and create.
