Artificial light can't be blocked atm, it's not a problem with the dashboard

I agree the headlight brightness at night is getting accurate to life. I've found in real life that certain types of headlights have been particularly bad at night, especially some older designs. The worst are the large rectangular headlights used in the USA during the 1980s and 1990s. They were OK on cars, but the higher off the road they were mounted, as on trucks, the lighting got very poor and dim. The small rectangular headlamps didn't have that problem; they were generally good. Newer aerodynamic headlights used in the US have varied widely in how well they illuminate the road ahead.

If there was one thing I'd change about the headlights in the new lighting, it would be to add more light scatter to the side. The beam is focused almost strictly straight ahead. In real life, there is more dim light scatter to the sides, which is actually helpful when approaching parking spaces -- you can pick put the lines in the dim side-scatter from the headlights and turn into a space more easily. The current headlight behavior doesn't have much side scatter, so finding a parking space in the dark is harder than in real life.

This “side-scatter” may just look useful but the real reason is safety. You just see pedestrians and bicyclists so much better. The more when you’re going around a corner. It’s asymmetric so as to not blind oncoming traffic. There are probably many different rules about this across the world so I don’t what’s the case in the US.

The asymmetric headlight beams is a European thing that North American vehicles don't have. Even European cars sold in North America have the North American headlight beam pattern. American headlight beams shine in a symmetrical pattern.

Nice find! It's one of the things that have to be changed when a vehicle gets exported across the pond.

You can also note, that English cars, have beams asimetric in opposite way that showed on pictures, due to driving on left - not to blind drivers coming opposite way.

The beam pattern defines the principal forward illumination that the driver sees as well as the rough "cone" of light that oncoming drivers are exposed to. Whether North American or European-spec, however, there's still minor dim "scatter" beyond the edges of the beam focus that's caused by reflection from the road and the normal behavior of non-coherent light. That's the part that's useful and second-nature to use for picking out things close to the vehicle in the dark.

The new headlights display the main beam pattern very well, and the edges of the beam pattern fade out nicely, but also fade out into total dark. There's not much, if any, ambient scatter of glow beyond the headlight beam. Now, without ray-tracing, that may be a bit difficult to replicate without some sort of "fake" glow added. But headlights don't behave like lasers; they have a primary focused beam created by their lenses or reflectors, but normal non-laser light also scatters. The transition from the headlight beam and glow to the surrounding dark cuts off very quickly in the game. In real life, the glow provides some useful close-up illumination for a small distance beyond the side of the truck.

strange. I thought it's reason is brighten it's own lane and also right side and also to not to disturb the car from opposite direction. same for britain (left side)

btw new bmw, audi, mercedes have a strange technology. they call it matrix led in audi, and intelligent headlight technology in bmw. headlight's detecting cars and reduces it's light automatically in front of opposite car to not disturb.

I'm sorry for the explanation. My English is insufficient in technical stuff.

Your explanation isn't bad. Basically these headlights light up a broad and long area like high beams and use a variable lightmask (hear, hear!) that shadows areas where oncoming traffic and even pedestrians are.

It's amazing idea as long as it works... In some years all those fancy lights systems will brake. You will have to change whole lamps which will be expensive.
