Drivers Tend To Kill Pedestrians At Night. Thermal Imaging May Help.::Pedestrian automatic emergency braking (AEB), which may become mandatory on U.S. cars in the future, tends to not perform well in the dark.

In IIHS’ latest tests of car headlight systems, fewer than half (43%) earned a good rating. [...] “Vehicles that earn a good rating for visibility in our tests have 23% fewer nighttime pedestrian crashes than those that rate poor.”

That's a lot of room for improvement without new technology.

It's the kind of thing you assume would have been empirically tested and have minimum safety regulations, instead of the wild variability we see from dimly lit up close to blinding pulsar from alpha centauri.

There is a minimum and regulations, in the US IIRC the legal range is between 500 and 3000 lumens. And it results in exactly what you describe.

Exactly.

We need to have regs targeting specific performance metrics based on testing.

Europe actually has incredible adaptive headlight technology that AFAIK was illegal in the US up until very recently. It'll be great to see this rolled out here as it's better for everyone.

Do we? I think they're really annoying, blinding the shit outta me, then finally adjusting correctly just right before we pass each other.

I'm curious what their "good" rating entails. Hopefully not just brighter lights, that just makes oncoming traffic blind. That could end up being more dangerous overall, even if it's not the car with "good" headlights doing the killing. Realistically, if you're going to walk at night somewhere there are cars, wear a light, high vis vest, reflectors, SOMETHING.

We have the tech, what needs to improve are regulations based on performance instead of tech.

That would leave room for innovative design that achieves the performance requirements.
