A new patent claimed by Tesla has revealed some additional details on the upcoming Robotaxi’s Sanitization System – which will automatically sanitize enclosed spaces. It discusses how Tesla expects to use this system, including some hints on the upcoming Robotaxi app. Rimac also recently announced their upcoming robotaxi, which looks a lot like what we may see in Tesla’s Cybercab.
Most interesting is that this patent isn’t strictly based on some specific systems in the Robotaxi itself but is rather based upon an overall routine and process for sanitizing enclosed spaces that are shared among multiple people, particularly around vehicle interiors. This means it is likely applicable to all of Tesla’s vehicles.
You can view the entire patent here, although we went through it all so you wouldn’t have to.
Sanitization
The sanitization patent is focused on observing and analyzing the conditions of the closed space and then generating a sanitization routine based on the conditions, and then finally executing it. This essentially means that the system will scan a vehicle, determine what kind of cleaning is required, and then conduct that cleaning.
Analysis - Interior & Exterior
Let’s take a look at the analysis portion first. There are a few key detection parameters – ambient temperature, humidity, the presence of pathogens or unclean air, and the presence or absence of certain conditions in the enclosed environment. Using a multitude of sensor data, including some from the vehicle itself, the system will create a sanitization plan.
The robotaxi's interior
Not a Tesla App
The sanitization plan doesn’t just include the interior of the vehicle – but can also consider external parameters like weather and vehicle usage history. Rain, snow, and mud could be some pretty big factors for a Robotaxi cleanup, and taking these into account is essential.
How It’ll Clean
Once the plan is generated, the system will utilize various sanitization routines, based on the plan that was generated. This can include using the HVAC systems, using UV lighting, using steam generators, and a few other processes. The system can also take into account whether the sanitization process can be accomplished by the resources available – e.g. if there is a human or humanoid robot available to accomplish some of the tasks.
There are a few basic methods described in the patent on how Tesla expects to sanitize vehicles, including blowing warm air toward the steering wheel, doors and windows, and the central display to sanitize. It also has a method to expose various parts of the vehicle, including the seats and seatbelts, to a sanitizing UV light.
There are some interesting and unique methods – using active or passive elements to create heat and sanitizing surfaces like the central touchscreen. That’s not all – the patent also talks about tilting the vehicle’s central display to reflect the sanitizing UV light around the vehicle. Tesla has some unique ideas on how to implement its automated sanitization process.
If there’s additional sanitization needed, the system can cooperate with external service robots (possibly Tesla’s Optimus), to sanitize the interior and exterior of the vehicle. It can also direct the Full Self Driving system to adjust the vehicle’s orientation, exposing certain parts of the interior to sunlight.
When and Where to Sanitize
Tesla expects this sanitization routine to begin running immediately after a passenger exits the vehicle, reducing downtime as much as possible between potential passengers. If the sanitization system identifies that deeper cleaning is needed, the system will redirect the vehicle in need of cleaning to a cleaning location, while another vehicle will be directed to the next potential passenger.
There are some Robotaxi-unique features, such as a disinfecting spray system and special disinfecting UV light that are not present in any of Tesla’s current vehicles. Whether these current vehicles will receive a refit or a refresh to include these features remains up in the air at this time, however, the patent did notably use the Model Y as the figure vehicle.
Some other features, such as using humidity, temperature, seatbelt retractors, seat adjustment motors, and motorized vents – are already in every Tesla vehicle.
Killing Germs
One of the most unique things about this patent is Tesla has looked at various airborne pathogens – such as SARS-CoV-2 (COVID-19), amongst others, and identified what temperatures and humidities will kill these off. It will use this information to change the ambient environment in the vehicle to one unsuitable for pathogens to survive, helping to prevent illnesses from transferring from one passenger to the next.
We’re going to see some unique things at Tesla’s Robotaxi unveiling on 8/8, and some more details of how this system functions will probably come up then. Sanitization of Robotaxis is absolutely one of the key steps that will help to build Tesla’s ambitious Robotaxi fleet – and we’re hoping to see more on how they expect to charge Robotaxis in the upcoming weeks.

Tesla is holding its 2025 Q1 earnings call today at 2:30 pm PT / 5:30 pm ET / 9:30 pm UTC. The earnings call will be followed by a Q&A session with Tesla executives, including Elon Musk.
We expect the focus to be on Tesla sales for the quarter, FSD Unsupservised and the Robotaxi network. Tesla may also discuss its upcoming, more affordable model, Optimus, and other products.
Listen Live
The event will be live-streamed on Tesla’s site. It is also expected to be streamed on X and YouTube like it has been in the past. Tesla has changed this from an Earnings Call to a Company Update, but it’s unclear whether the phrase change holds any significance in what will be shared.
Update: You can listen to Tesla’s earnings call live below. If you prefer, you can also listen live on Tesla’s website.
Start Time
Tesla's live stream starts at 2:30 pm PT, which is the following times around the world:
2:30 pm Pacific Time
5:30 pm Eastern Time
10:30 pm UTC
10:30 pm - London, England
11:30 pm - Berlin, Germany
9:30 am (April 23rd) - Sydney, Australia
Q&A Questions
The questions asked during the Q&A portion of the call come directly from investors. These are currently the top-voted questions, so we’ll likely see answers to several of these questions:
What are the highest risk items on the critical path to robotaxi launch and scaling?
When will FSD unsupervised be available for personal use on personally-owned cars?
Is Tesla still on track for releasing “more affordable models” this year? Or will you be focusing on simplified versions to enhance affordability, similar to the RWD Cybertruck?
Does Tesla see robotaxi as a winner-take-most market, and as you approach the Austin launch, how do you expect to compare against Waymo’s offering, especially regarding pricing, geofencing and regulatory flexibility?
Can you please provide an update on the unboxed method and how that is progressing?
How is Tesla positioning itself to flexibly adapt to global economic risks in the form of tariffs, political biases, etc.?
Does Tesla still have a battery supply constraint (noted on Q4 ER call) and how does this change w/tariffs?
Did Tesla experience any meaningful changes in order inflow rate in Q1 relating to all of the rumors of “brand damage”?
Regarding the Tesla Optimus pilot line, could you confirm if it is currently operational? If so, what is the current production rate of Optimus bots per week? Additionally, how might the recent tariffs impact the scalability of this production line moving forward?
Robotaxi still on track for this year?’
Look Back at 2025 Q1 Numbers
Most of Tesla’s Q1 deliveries, 323,800 units, were unsurprisingly for the Model 3 and Model Y, while the “Other Models” category (including the Cybertruck, Model S, and Model X) accounted for 12,881 deliveries.
Comparing these numbers to Q1 2024, the Model 3/Y is down about 13%, while the Model S/X and Cybertruck are down about 24%.
In terms of production, Tesla built 345,454 Model 3/Y vehicles and 17,161 from its “Other Models” line. The company attributed the production drop to the Model Y changeover but stated that the ramp is “going well.” However, deliveries and production were both down year over year.

Although Tesla doesn’t officially break down its numbers by region, Troy Teslike, who closely monitors Tesla's delivery and production numbers has provided estimates that show Tesla’s deliveries across regions. Tesla delivered the most vehicles in China this past quarter, so it’ll be interesting to see if this trend continues.
His estimates for the regional break down are below:
Tesla’s Giga Texas factory usually gives us the first site of Tesla’s upcoming products. We first saw the Cybertruck and Model Y castings here. With Giga Texas being one of Tesla’s largest factories, it’s logical that most products would originate here.
Tesla has also stated that it intends to manufacture the Cybercab, Semi, the next-generation vehicle, and Optimus at Giga Texas over the coming years. The affordable vehicle and Cybercab were originally intended to be manufactured at Giga Mexico, but the plans for that facility were waylaid by changes in economic policy.
Robotaxi Castings
These new castings were spotted by Joe Tegtmeyer, who regularly does drone flights of Giga Texas. Joe pointed out that these castings don’t look like the usual Model Y or Cybertruck castings usually seen outside Giga Texas.
With an eagle eye, @minusYCore on X also spotted some interesting text on the frames holding the castings up. In particular, the castings say “RTTX050” and “W68-RSF AS-CAST”. These could be interpreted as ‘Robotaxi Texas’ and ‘Rear SubFrame,’ as Tesla marks Cybertruck castings as “CTTX.” The as-cast portion indicates that these particular castings haven’t been trimmed yet, according to the X user.
The castings laid out.
@JoeTegtmeyer
The size and shape of these castings—combined with rumors that Tesla’s more affordable vehicle has been delayed—suggest that these castings are intended for the Cybercab.
These castings are much flatter and appear to be a different size than the castings found throughout Giga Texas, indicating that they are intended for an entirely different product.
It’s possible that these are the first castings used by Tesla to test their unboxed assembly process, which the Cybercab is expected to rely on. If you take a closer look at the video below, you’ll note that these new castings look very similar to the ones in the unboxed assembly video.
Interestingly, Tesla did say that they don’t intend to have the Cybercab available for customers before late 2026 or early 2027, but we’ll likely hear updated timelines as Tesla’s Q1 2025 Earnings Call tomorrow.
A more vertical look at the castings.

New Giga Presses
To top it all off, new parts for a Giga Press - the machine Tesla uses to make these castings - were also sighted in Texas. These machines are few and far between, and each one is highly specialized for the particular vehicle it produces. Seeing new parts coming in usually indicates that a new assembly line is under construction, or that changes are being made to an existing line to either expand it or update it.
There’s a lot happening and we will hopefully know more tomorrow evening.
