Tesla Adds Full Windshield Wiper Controls to the Steering Wheel in Software Update

You can finally control the windshield wipers from the steering wheel in the Model 3/Y

Simon

Tesla's latest 2023.20 software update brings an addition that fans have been eagerly anticipating - the ability to control windshield wipers from the steering wheel. This latest enhancement adds another layer of convenience.

When Tesla introduced its steering wheel customization feature in the 2023.12 update to the Model 3 and Model Y, many were puzzled at the omission of windshield wiper controls. The initial setup offered many features, including controls for the glovebox, defrost, dome lights, climate temperature, HVAC fan speed, display brightness, dashcam video, acceleration mode, steering wheel heat, and the backup camera. Surprisingly, the ability to control wipers from the steering wheel was not included.

The Finer Details: Exploring the New Wiper Controls

The newly added wiper controls allow drivers to adjust the speed of their windshield wipers directly from the steering wheel, without having to activate the wipers first.

In the 2023.12 update, Tesla added the ability to adjust the wiper speed by tilting the scroll wheel left and right, but this only worked after pressing the left stalk button to activate a single wipe of the windshield.

With this update, Tesla is bringing full wiper control to the steering wheel, letting you adjust the speed of the wipers, turn them off or set them to auto.

As with the other steering wheel controls, customizing the wipers feature can be done by navigating to Controls > Display on the touchscreen interface.

Unveiling the Future: Auto Wiper v4 System

While our focus is primarily on the windshield wiper controls on the steering wheel, it’s worth highlighting another significant improvement that Elon Musk has tweeted about for the upcoming Auto Wiper v4 system. Musk mentioned, "Actually, smart auto wiper software releases in about three weeks." That was about three weeks ago. While Musk's timelines are often optismistic, it looks like we may have an improved wiper system to look forward to.

Breaking Down Auto Wiper v4

Auto wipers v4 is set to overhaul Tesla's current wiper system by integrating video from all of Tesla's onboard cameras into a single 360-degree view, according to Musk. This innovative approach will provide the system with a better understanding of weather conditions, leading to a more accurate and responsive wiper system. Musk acknowledges the need for improvement in this area, referring to it as "one of the last neural nets Tesla is updating from a single camera, single frame NN to surround video."

The 2023.20 software update, features many lesser known improvements, where the new windshield wiper controls are just one of the many improvements that didn't appear in the release notes for the update. Check out the full list of unlisted changes in Tesla's 2023.20 update.

Tesla Smoking While Supercharging? A Look at What's Actually Happening

Hot_Engineering3140 on Reddit

Winter is here, and temperatures are dropping, so one of the most common Tesla questions is about to resurface.

If you’ve landed here after frantically searching about “smoke” coming from your Tesla while Supercharging, take a deep breath—it’s completely normal.

Tesla Smoking While Charging

If you’re Supercharging in freezing weather—even with preconditioning—you might notice steam rising from your Tesla. But rest assured, your car isn’t smoking.

Your Tesla’s heat pump is hard at work warming both the cabin and battery to keep you comfortable and ensure optimal charging temperatures. Over time, condensation and ice build-up in the heat exchanger coils.

Why Does It Happen?

When you reach a Supercharger with your vehicle, the heat pump is still running hot, but without the cold air from driving to keep the heat exchanger coils cool, the ice and condensation quickly start to evaporate—creating what looks like smoke.

Since this typically happens near the front of the vehicle, where a car would traditionally have an engine, new vehicle owners can be startled by the discovery. However, rest assured that it’s just water vapor and it’s completely normal in cold weather.

In fact, this behavior can be experienced in any EV with a heat pump in cold climates. So, if you saw steam coming out of your vehicle and panicked, don’t worry—you’re not alone.

Now that you know what’s happening, go ahead and Supercharge with confidence.

Tesla Improves YouTube App With Smoother Playback

Not a Tesla App

Tesla made a lot of improvements in the 2024 Holiday Update, including more than 15 undocumented improvements that were included in the release. One of these was a stealthy performance improvement to the YouTube app.

Several people have mentioned they’ve seen improved performance on YouTube since this year’s Holiday Update - and there’s an interesting reason why.

YouTube Improvements

The improved YouTube performance in Tesla vehicles comes from an unexpected source—Tesla actually rolled back support for YouTube’s newer AV1 video encoding. Instead, vehicles now default to the older VP9 encoding standard.

While AV1 is highly efficient in terms of bandwidth, it requires considerably more processing power to decode and display videos. VP9, on the other hand, is less computationally demanding but uses more bandwidth to achieve the same video quality. This trade-off means smoother playback and better overall performance, even if it comes at the cost of slightly higher data usage.

Intel Inside

The VP9 video codec that the YouTube app is now using is much easier to decode, making it less taxing on the vehicle’s processor. This change is particularly beneficial for Tesla vehicles with Intel processors, which previously struggled to stream video at just 720p. When using AV1, these vehicles often experienced stuttering, sometimes forcing the YouTube app to automatically downgrade playback to 480p.

With this update, Intel-based Teslas should now be able to stream at 1080p smoothly. Streaming at 1440p is also possible, although occasional stutters still occur as the system keeps up with the decoding process.

Intel-based vehicles are the big winners with this change, but this appears to affect AMD Ryzen-based infotainment units as well, providing even smoother playback.

Chromium Web App

Tesla’s Theater apps aren’t native applications; instead, they run as chromeless web apps, leveraging the open-source browser built into Teslas known as Chromium (the open-source version of Chrome). Although this works quite well, there is a severe limitation - Chromium hardware acceleration isn’t supported on Linux, the operating system Tesla uses for their OS.

As a result, Tesla vehicles rely on software decoding instead of hardware decoding, which would otherwise handle video playback far more efficiently. A potential solution could be for Tesla to transition away from Chromium-based web apps in favor of a Mozilla Firefox-based browser, as Firefox does support hardware acceleration on Linux. This switch could also open the door to better streaming performance and the possibility of expanding Tesla’s in-car entertainment options.

However, Tesla’s choice of Chromium likely stems from Digital Rights Management (DRM) requirements for streaming services like Disney+ and Netflix, which rely on DRM-enabled playback. Firefox on Linux has had inconsistent support for DRM due to codec availability and variations in operating system versions.

We’re hopeful that Tesla will either adopt Firefox or develop a fully native application to improve video streaming, rather than continuing with the current web-based Tesla Theater. This shift could also pave the way for additional in-car applications built on Tesla’s native Linux environment—perhaps even reviving the long-rumored Tesla App Store.

Regardless, this update is a welcome improvement, particularly for YouTube, which remains one of the most widely used Theater Mode apps due to its accessibility, free content, and mix of short and long-form videos. It remains to be seen whether similar improvements are made for Netflix, Disney+, or other streaming platforms.

If you’ve noticed improved performance in Theater Mode, now you know why.
