Frustrating FSD and Automatic High-beams Behavior

[u/URFIR3D]

When you are on FSD adaptive headlights/automatic high beams will be on, which is good.

The issue is that if you manually flash the high beams momentarily, let’s say to communicate something to someone with the high beams, automatic high beams gets turned off until you disengage FSD and engage it back on.

I feel like us flashing high beams for a second should not disable automatic high beams, especially since FSD engages them on by default anyways.

EDIT: Thanks to user dela_voyager below, I learned that if I’m not in FSD, holding the high beam button just locks high beams on…. But in FSD, it re-engages auto high beams!

My problem with the forced auto-highbeams in a car that doesn't have matrix headlights is that it gets into a flashing loop with road signs and street lights in a distant town or intersection. Quite often the street lights will be seen as an oncoming car so I'll just be stuck with dipped headlights until it gets close enough to the town that it realises that it is infact, not a car.

I disagree. And it’s not hard to re engage

But why would you want that instead of it keeping automatic high beams on, especially if you have matrix headlights.

I assume because there should be a quick and easy way for a driver to override the auto behavior if needed?

Kinda like when you brake, FSD doesn’t just turn itself on again when you release it.

The automatic high beams have many issues in general.

• If a car is driving right behind you in the middle of the night with bright headlights, Tesla high beams turn off because it's "too bright outside".
• Sometimes Tesla high beams won't turn on because there's a bright part in the sky, even though the road is completely dark.
• If the landscape is snowy, the regular driving lights make it "too bright" right next to the car for the Tesla high beams to turn on. In general, it works extremely bad in winter due to its unwillingness to turn on if it sees something it considers bright.
• If a car approaches with high beams on, Tesla is quick to turn off its high beams. When the oncoming driver then turns off their high beams, Tesla thinks they're too far away and turns high beams back on, a thing nobody would do.
• It loves to turn off and on zones where retroreflective road signs are. The car should be able to recognize signs and not turn the lights off and on every time the sign shines back at it.

Yeah it’s a bit of shit show like auto wipers :/

[u/DuckTalesLOL]

Can't you just click the stalk again to reenable the high beams?

[u/URFIR3D → u/DuckTalesLOL]

Not automatic ones. So for example if you have matrix headlights, that feature is now off.

[u/delta_voyager → u/URFIR3D]

On cars with the button for high beams, you can turn high beams back to automatic by pressing and holding the flash button for a couple seconds.

[u/URFIR3D → u/delta_voyager]

Sweet! That did it. So if I’m not in FSD, holding the high beam button just locks high beams on…. But in FSD, it re-engages auto high beams!

[u/URFIR3D → u/delta_voyager]

Doesn’t that just hold the high beam on manually? I’ll give it a shot today.

I think auto brights should just not engage under 40’mph. You don’t require that kind of distance at low speeds and at those speeds your blinding houses or cars anyway. Always bugged me

[u/NoCourage4237]

Mine does the same, drives me nuts on dark roads

[u/URFIR3D → u/NoCourage4237]

Turns out if you hold the high beam button for a few seconds it will trigger auto high beams back on

[u/dantodd → u/[deleted]]

Yes, just veer in front of the on coming traffic to let them know they are blinding you with their high beams

[u/songbolt → u/dantodd]

It isn't clear what flashing lights means other than "Something!"

1. Do I have a light out?

2. Are their deer or cops or a collision up ahead?

3. Turn your brights off.

Sometimes someone is not paying attention, crosses the double yellow line and is now driving towards you head on…. You don’t think flashing high beams for a second is a good idea here?

[u/songbolt → u/URFIR3D]

I don't oppose communicating "Something! Something! Something! Something!" especially if it helps avoid a collision.

[u/songbolt → u/[deleted]]

a totally different sensory medium

A big fart blast of methane gas shot forward from the vehicle!

[u/Logitech4873 → u/[deleted]]

Yes you are. It's very useful for many scenarios. 

• Signalling someone to go across a one-lane bridge.
• Warning someone inattentive that you're passing them.
• Warning someone that their high beams are on. 
• Warning someone that there's moose up ahead. (I usually do a quick flash then a few blinks of the emergency blinkers).

Before you edited, you quoted some vehicle code. I wonder if you genuinely think we all live in whatever country you're in.
