Yes, it works much better on my new Model Y (2024) than my old Model S (2014). But they didn't really solve the original problem, i.e. detecting oncoming traffic vs. street (or other lights) up ahead. The matrix led's darken these areas in any case, and neither street lights or oncoming cars complain of course. But it does not fill me with much confidence.

> Wipers, dunno, they used to be really bad but I have not noticed the issue in the past few months, maybe they have done something.

Then that software update has not come to Norway at least, here they still start wiping in dry conditions, and fail to detect actual rain; so they need to be manually started all the time.

Isn't this the problem with AI though? We've taken something we don't fully understand (neural networks) and applied them. We can give them a lot of training data to the point where they seem to be able to do stuff on their own. But when they fail, we really cannot do anything besides adding new nodes to our network and add more training data, and hope for the best. We cannot really say what went wrong, and fix it.

>they still start wiping in dry conditions

That's for safety if a flake of dirt or dust lands on the front window right over where one of the cameras are, it will do a wipe and try to get rid of the thing that is distorting the image. Or it will do it if you are driving straight into the sun sometimes, presumably because it's doing a best efforts action in case the visibility problem is further exacerbated by dust which can be cleared.

It's strange to me that actual helpful features are misinterpreted as flaws, but that's how it is with new technology I guess.

Failing to detect actual rain, yes I see that too a little sometimes. I think they should augment with audio detection. There is a microphone, obviously, for the speech button, and depending on how things are wired sometimes speaker cones can also be repurposed as microphones.

Automatic wipers are not new technology and their implementation on cars that use actual rain sensors is much better than Tesla’s.

Not that dry conditions. I live in Trondheim, where it rains/snows well over 200 days a year, so it's not wiping off some dry dust of the camera area. It just starts wiping the clean window in perfectly fine weather. At other times it rains quite a bit and it does not come on.

The software update to soft click the left stalk to engage the wiper menu via the left steering wheel roller is a nice quick fix for these situations, so they are doing something.

I was not saying that there absolutely is always dust there. I was saying the system is doing a best efforts action just in case there is dust or snow or other debris there which there sometimes is. I'm guessing they have birds in Trondheim.

I haven't tried the roller for the wiper menu, thanks for the reminder. Less rain around here.

I guess that could be the case; but they do seem quite random.

We do, mostly seagulls where I park my car :-) But you're not dry wiping away anything they produce, that takes a good scrubbing.

It makes the experience fully controllable from the steering wheel using one hand, which is very good. One light press on the left stalk, and the menu pops up down on the left corner on the screen where you can roll to your preferred setting. I hate having to go into menus on the touch screen while driving.
