If thats the case then they could just add the IR into the camera housing on the windshield and call it a day with the HW4 cam replacements that might be coming.

But that goes against the “Vision Only” dogmaIf thats the case then they could just add the IR into the camera housing on the windshield and call it a day with the HW4 cam replacements that might be coming.
No, I have infrequent phantom braking but it's not that bad.Same question for you. Do you have poor Driver Assist performance, such as excessive phantom braking?
It may save a dollar, but I think the real motivation is that Tesla wants to be vision-only, and they are sticking to this as a matter of principal even though it doesn't work as well in some applications, like auto wipers and high beams. As their technology matures maybe one day the wipers will work better, but it's frustrating for now.Just like with radar and ultrasonics someone at Tesla dictated the removal of the IR in late 2016 and directed the engineers to fabricate a magic replacement in order to save a buck.
Wow, very cool!Here, build your own:

This system can monitor when a sheet of glass has either water or ice on its surface, and then generate a PWM signal to control a motor that wipes away the liquid from the glass...www.electronicdesign.com
Wait. How do you think auto high beams work in other cars? They use either one or two forward facing cameras. The system has to detect headlights in the oncoming lane at distance. But it also has to the detect taillights of nearby vehicles in the same lane. All these systems use "vision".It may save a dollar, but I think the real motivation is that Tesla wants to be vision-only, and they are sticking to this as a matter of principal even though it doesn't work as well in some applications, like auto wipers and high beams.

When did you take delivery of the 2023 MIC MY Steve?Hi,
We have a 2023 MY Shanghai built Model 3 Performance - with USS.
Interestingly - I reverse the car into my garage and the front of the car is just a few feet from the automatic roller door.
When I get in the car and put on my seatbelt and put it into drive - the screen is showing an object In front of the car (the garage door)
I then open the door with the remote control and wait for it to fully raise.
When I then move forward - the display is still showing the object in front of the car (‘which is no longer there) and even shows me getting nearer to it!
So - the existing USS already has some sort of “persistence of vision” function!
Cheers
Steve
Thanks for the info. Now that you mention it, it does make sense that a camera would be required to discern headlights and tail lights from just plain bright stuff or reflections. So if they've got the required hardware, I wonder why their algorithm is so poor? I would have guessed that determining when to use the high beams would be a lot less complicated than autopilot.Wait.

The problem with the Tesla system is that the algorithm is garbage.
My guess is that auto high beams are a low priority for improvement, just like auto wipers.Thanks for the info.

Yeah, they didn't do any changes to auto high beams for a long time. They only recently worked on improvements:My guess is that auto high beams are a low priority for improvement, just like auto wipers.
Took delivery on 1st November.When did you take delivery of the 2023 MIC MY Steve?
I have found auto high beams to work great lately. Wipers are another story. Part of the difficulty is that they are designed to work for the camera, not the driver.Yeah, they didn't do any changes to auto high beams for a long time. They only recently worked on improvements:

Auto high beam works great for meI have found auto high beams to work great lately. Wipers are another story. Part of the difficulty is that they are designed to work for the camera, not the driver.
Yep, that's the point a lot of people miss. The auto wipers only care if the view is clear for the camera, it doesn't care if the windshield is obscured. A lot of the actions make more sense if this is kept in mind.I have found auto high beams to work great lately. Wipers are another story.

If USS were to be used for parking, it would never park in my garage. Everyday when I park, all is does is ding ding and red lines.In the coastal area of Norway this is more the standard 8 months of the year and this is not WHEN it is raining but after driving on wet roads.

Is that why the price cuts announced 2 days ago because the vehicles don’t have USS and probably will have in April?I still don’t see cost savings as a credible explanation for the removal - or for the timing of it at least. It’s such a trivial amount in the scheme of what it costs to build a car, and it leads to a direct loss of (as has been widely observed!) a very fundamental feature.
My interpretation is that this was always part of the roadmap but the timing has been forced by a shortage in supply of the necessary components. Rather than deal with the shortage as other manufacturers have they’ve decided to ‘fix forward’ and embrace it.
I hope they return the functionality with at least a similar level of performance soon. I wonder whether Tesla expected to have it rolled out already but have had FSD related delays that have blocked it.
More likely due to inventory piling up right now, I'd give it a few months at the most and then they raise the prices again. This is of course, like a lot on these forums, speculation.Is that why the price cuts announced 2 days ago because the vehicles don’t have USS and probably will have in April?
They are passing the savings from the USS to the customerIs that why the price cuts announced 2 days ago because the vehicles don’t have USS and probably will have in April?
Looks like this aged well ))Hi
Just spoke to Tesla Westmont advisor she said update to software for the lack of USS should be less than 2 weeks, "very soon". Hope she is right!
