For that size windshield I don't think you could do a single big wiper like that unless it did more than just pivot. The arc in the illustration shows why. The wiper on the semi does more of a side-side action.
I agree. The combination of size of single wiper and the slope/angle of the glass will put a lot of stress on the wiper at highway speed. If they don’t use a high tech solution, side to side has less drag.

Maybe the notch is for a charge port? I could see why top mount charge port could require extra thought. There could be manufacturing efficiencies by not cutting into steel paneling.

I am certain they were like, “oh, where is the windshield wiper going to go. Right… we need a spot for that.” So they angled the bottom corner to make a spot for the windshield wiper and cover plate. It will probably be glossy and match the other corner.

I have no idea what Tesla is going to do on the Cybertruck. Patents are often red herrings. Filed but never used or used in a product 2-3 generations out.

The linear wiper idea is certainly intriguing.
That is true about patents. I don’t think anybody the ones I have written ever saw productization. I mentioned the electrostatic wiper because it is very realizable and clearly Tesla doesn’t like current wiper technology.

Looks like I am going to be an even better Rain X customer.in the future.

The writer of this article feels that it is the Cybertruck windshield. Sorry, but the photos accompanying the article would not transfer. (Admin. - I kept getting a “Sorry, try again or contact the administrator” message.)

Tesla shares its glass technology that makes it quieter, tougher, and safer from UV radiation
  • Iqtidar Ali
  • September 18, 2021
https://www.teslaoracle.com/2021/09...es-it-quieter-tougher-and-safer-from-uv-rays/


In a new video recorded at the Tesla Design Center in Hawthorne, California, Tesla Glass Director Mike Pilliod explains how Tesla has made its vehicle glass tougher, quieter, and safer from ultraviolet exposure.

Mike demonstrated the acoustic insulation performance by sliding up his Model Y glass, the noise from outside suddenly dropped to almost zero. He also shared two design sketches of the Tesla Model Y (interior and exterior) that introduced the concept of the full glass roof from the front to the rear of the vehicle.

Turning this concept into reality took a large amount of R&D effort at the Tesla Glass Technologies Center, “We spent a ton of time making sure that each glass position is the right curvature, is the right size and shape in order to give that seamless approach,” Mike explained.

Laminated Double-Glass Side Windows
Since Tesla, Inc. practices constant improvement and innovation across the company, the Silicon Valley-based automaker improved its glass technology over the years. The new laminated double-glass side windows are now implemented in the entire lineup of vehicles. Tesla Model 3 received this upgrade with the 2021 Model 3 refresh.


Tesla has placed an acoustic dampening layer between the side window glass outer and inner layers that reduce road and wind noise during drive. Even when the vehicle is stationary, the outer sound pollution is minimized by this new technology.

Owners of older Tesla vehicles had complaints about the noisy cabin, especially the Model 3. But with this new technology, Tesla has taken care of this complaint. In addition to this, the 2021 Tesla Model S also has Active Noise Cancellation (ANC) to make the vehicle cabin feel even quieter.

UV Radiation Protection
The expansive glass roof is the specialty of all Tesla vehicles, to protect the occupants from heat and UV radiation of the sunlight, Tesla has implemented multiple layers of films in the glass.

Antonio, a glass specialist at Tesla explains in this video (below), that a 2% tint film is combined with other different types of films that reflect solar radiation. A PVB (Polyvinyl Butyral) film combines all of these layers to increase the toughness and flexibility of the roof glass implementations in other areas of a Tesla vehicle.


A Tesla roof absorbs 99% of UV radiation itself. This makes the cabin amazingly safe even though the occupants have a large open experience inside the vehicle.

Toughness
Tesla claims that the glass roof in its vehicles can withstand 4x the weight of the car. This has been practically demonstrated in several Tesla crashes we have seen over the years. Like a Tesla Model 3 rollover accident in China last year, the glass roof stayed intact despite the vehicle rolled multiple times.


Before putting the cars into production, Tesla extensively tests the toughness and safety of its proprietary glass with rollover and roof crush testing. After these tests, Tesla puts the glass through thermal tests, Mike further explains in this video.

Glimpse of the Giant Cybertruck Windshield Glass
Tesla also showed the giant Cybertruck windshield glass in this video for a few seconds. This must be one of the spare windscreens for the prototype Cybertruck that is under the use of Elon Musk usually.

Like Musk breaks the so often they need to keep multiple spares hanging around.

What a stupid theory. This one doesn’t even look like it would fit quite right into the prototype.

Even if they weren’t working on the beta trucks, it makes sense they would be making panes for testing.

I suspect the lower left hand side angular cut in the base of the windshield is holding a secret regarding the production windshield wipers. I predict it will be for a wiper assembly/motor that will drive a single articulating wiper arm with a LONG blade attached.

I also noticed the lower right hand corner of the windshield has a semi circle notch cut into it(?). You can plainly see the top section where the black area has a “Y” for the front facing cameras to sit in.

I have a friend of a friend who works in the glass area of Tesla. He helps to develop prototype auto glass for future Tesla vehicles. I am guessing that he signed a NDA since he doesn’t talk about work except for general stuff like heating glass sheets over molds, etc.

I hope that Rain X doesn't cause the laser wipers to bounce off the glass and hit a police helicopter pilot in the eyes. Could accidentally cause some serious issues.

In the discussion about Alon they said it is so smooth it acts like RainX without it. I know that video is almost 2 years old but worth a watch.

Yeah, high hardness glass is crazy slick. My last phone had some on it and I couldn't put it on even the most imperceptible incline or it would slide off.

Well sorry folks, I think that windshield is for my cybertruck, due to roll off the line and into my driveway.
