That seems very reasonable? If the auto high beams aren’t accurate, that’s a problem. But if I’m driving I want control of the lights, and you can’t fault the self driving system to think the same? As long as it doesn’t want to control the playlist on the stereo…
- toomuchtodo 5y agoVery reasonable. Cameras for front collision avoidance need as much visual distance as possible, hence the auto high beam requirement. High beams = more night distance. Tesla is hiring for a DSP engineer for electronic scanning radar, so the rumor is this is temporary (camera only safety systems) until they’re ready to deploy their own, more advanced radar sensor (trained off of the visual neural net) versus the crude Continental radar sensor they’ve deprecated.
- clouddrover 5y agoTesla should put lidar on the car and be done with it. That's what Lucid has done: https://electrek.co/2021/05/26/lucid-reveals-ux-intuitive-user-experience-on-upcoming-air/ https://electrek.co/2021/05/26/lucid-reveals-ux-intuitive-us...
- toomuchtodo 5y agoToo expensive for mass market. Lucid’s vehicle is almost $190k.
- siddarthd2919 5y agoCompare the 190K with Tesla Plaid fully loaded. Lucid also has a $69K model.

- _ph_ 5y agoThe point is, adding lidar to the car does not mean you are "done with it". If it were the case, Tesla would have done it long ago. Lidar is great for precisely detecting 3D surfaces. But it helps very little in characterizing those surfaces. Lidar could tell you precisely how far a sheet of metal is. Whether that sheet of metal is a traffic sign and what it says, it tells you not. Lidar doesn't detect lane markings and many things more. Also, there is the challenge of merging the Lidar data with your camera images.
- clouddrover 5y ago> adding lidar to the car does not mean you are "done with it" It will mean Tesla is done with trying to avoid adding it. They test with lidar so they might as well start using it: https://insideevs.com/news/508669/tesla-model-y-luminar-lidar/ https://insideevs.com/news/508669/tesla-model-y-luminar-lida...
- a_t48 5y agoLIDAR absolutely detects lane markings, along with street signs, if you’re close enough. Edit: the reason here is that road paint (and the marking on a sign) is typically retroreflective, while roads (and regular painted sheet metal) are not. Retroreflective materials are very easy to detect with LIDAR. Even if you are on older roads that don't have retroreflective paint, white objects and black objects also tend to show up differently. Edit2: there's also no reason you can't use detection algorithms to characterize pointclouds. You can also fuse the returned objects from the lidar sensor(s) with the objects from the camera(s). You have the latter problem even with just multiple cameras. Inevitably, whatever you are using for segmentation/classification will return different results on different sensors, for sensors that share the same FOV - you do need a strategy for handling this. Tesla has not added LIDAR because of cost (and because of Elon's ego...) - they are one of the few companies going directly for consumer sales - more parts that cost $$$ and require calibration aren't good for that.
- giantrobot 5y agoLIDAR is used in addition to 2D camera images. LIDAR is used to build a depth map and do image segmentation and works in low light and low contrast environments. Single cameras (even stereo cameras) require a lot more assumptions about contrast and environment lighting to do image segmentation and depth maps. They're rarely as accurate as LIDAR and often far worse. Depth maps and image segmentation are the building blocks of object identification. You can try to AI your way into those with a single camera but it'll be less accurate and more error prone.
- BoorishBears 5y agoThe unreasonable part has to do with the reality of auto high beams. Even the best implementations dazzle other drivers. Auto high beams are only realistic when used where normal high beams are. That is, mostly on single lane roads with no dividers, little to no street lights, where opposing traffic is not appearing often, etc. - It seems like such a small thing compared to driving a whole car... but this is one of the few vision features that directly affects other drivers on a regular basis. The comments explain how for example, vehicles with tall ride heights like commercial trucks get dazzled due to their tailights sitting much lower than their mirrors It's just not realistic to leave your high beams "potentially on at all times" unless you're willing to dazzle other drivers.
- closeparen 5y agoThe "auto" in "auto high beams" is that they switch off for oncoming traffic.
- BoorishBears 5y agoIf only naming things based on their intended function made them work like that?
- FDSGSG 5y agoModern auto high beams work fine, but unfortunately modern headlights are illegal in the US. https://www.autoweek.com/news/technology/a34417809/nhtsa-still-hasnt-ruled-on-adaptive-headlights/ https://www.autoweek.com/news/technology/a34417809/nhtsa-sti...
- Hamuko 5y agoDo Teslas have matrix high beams?
- josephcsible 5y agoNo, because the government doesn't allow them.
- arkades 5y agoI guess less reasonable in the context of “they’re very unreliable, which is why I always keep auto high beams off.” It’s not an irrelevant bit of context.
- zwily 5y agoIn 6 years of driving Tesla’s, I’ve never even thought to turn off auto high beams. I’m not even sure how I would!
- riversflow 5y agoAs someone who frequently drives windy roads at night(I live on one), please learn how. Auto high beams are rude, they only turn down once my lights are on you, if we’re going through a corner, thats close enough to put after-images on my retinas. Frankly, I think they are a safety hazard that should be illegal. A human driver will see the headlights coming and turn their high-beams down preemptively. Its doubly shitty because cars outfitted with auto high-beams typically have those high intensity lamps too. Ugh.
- dragonwriter 5y ago> Frankly, I think they are a safety hazard that should be illegal. They are a safety hazard, and unless they consistently operate headlamps in accord with rhe applicable local law [0], using them already is illegal.

- jjav 5y agoThis is incredibly rude. Always turn off high beams.
- zwily 5y agoThey’ve never failed to turn off automatically when a car is coming in my experience. In fact, they turn off more reliably than if I was doing it myself.
- Aardwolf 5y agoOne question then is why it requires you to enable "Auto High Beam" manually If it wants auto high beam, it can just enable the setting itself, and restore your own preference if you disable autopilot (and even better: it can control the beams when autopilot is enabled, irrespective of any user settings, after all if autopilot can steer why couldn't it also change the lights)?
- judge2020 5y agoIt actually does enable them manually, it just doesn't re-enable them after the driver manually turns them off during autopilot.
- hadsed 5y agoLOL. let the car drive itself, but give up music control? over my dead body! it's funny to me because you'd expect music to be lower stakes and such, but it just highlights that actually driving a car is a much more well defined problem than picking the music i like
- jdmichal 5y agoHey! The rule is and always has been: Driver chooses the music!
