My parents' new Chevy Bolt automatically turns off the brights when appropriate. At first I was doing it manually but then I started trusting it, it just works, it does it at exactly the moment I would do it (actually it's better at it than me.) I'm surprised Teslas don't do it.

You must never drive on a curvy roads then. Every car I driven waits until the approaching car is fully around the corner, blinding them for a full second before dimming, instead recognizing the headlights around the corner and dimming earlier.

I don't even know what a Chevy Bolt looks like! Maybe the problem is every other model.

It's not hard to know when a car is approaching from corners / hills; there's light before they get there. I have fun manually adjusting the brights; I drive automatic transmission, lighting is the only fun I get.

Newer cars with matrix LED headlights account for this, such as the Volkswagen ID series. The brights not only "blot out" the shape of the cars around you, they also rotate when turning or going around a curve, so that you never accidentally point them at oncoming traffic.

It's quite magical and weird to observe in real time. When driving past oncoming cars, you can see a halo of darkness around each car. There are videos on YouTube that show the effect pretty well.

All Teslas can do this too, as can a huge range of modern cars with so called "auto dipping headlights". Virtually all cars with this option allow you to turn it off though...

The quality of the auto-dip implementation varies enormously as well.

Yeah, and the ones that auto dip usually don't have auto off mode. To bad they didn't leave it in as an option.

I am not sure that the incredibly bright Tesla Model 3 (and sometimes Model X) lights are on brights but are just stupidly bright at low-beam settings.

> I'm surprised Teslas don't do it.

They do. Also, the ones with matrix LEDs (most newer Models other than the Cybertruck) automatically create a circle of darkness around anything they detect to be another vehicle.

Why the downvotes? Jesus, I have a new Model 3 Performance and the matrix lights do exactly as stated.

Yup it is amazing, it also focuses illumination on signs and maintains that focus as you drive towards them.

ours does - and it does it very reliably as you describe the bolt above.
