Tesla Lead Engineer urges Rivian to optimize R2 for existing Supercharger Network
The Rivian R2 has received much acclaim from the electric vehicle community, and this is highlighted by CEO RJ Scaringe’s announcement stating that the company had received over 68,000 reservations for the upcoming all-electric crossover SUV. But while the Rivian R2 has earned praise for its price, specs, and looks, one aspect of the vehicle has raised eyebrows — its charge port location.
As could be seen in the Rivian R2 prototype that was shown off onstage, as well as the R3 and R3X prototypes that were unveiled after, the electric vehicle maker has opted to equip its upcoming vehicles with a charge port located on the rear passenger side. This, as noted by EV owners, would result in the R2 taking up two spots at Tesla’s V3 and V2 Superchargers.
EV advocate Chris Hilbert, who attended the R2 event, claimed in a post on X that Rivian was able to provide him an answer behind the R2’s charge port location. As per Hilbert, “Rivian is counting on the charging infrastructure to adapt over the next two years. Tesla should not dictate the port location. They are expecting (the) charge port location to not matter by 2026. They are also expecting the future to be curbside charging,” Hilbert wrote, though he also noted that Rivian employees were receptive when he told them that the R2’s charge port location was the vehicle’s only flaw.
I stopped back at the theater to talk to many @Rivian employees tonight. I told them this is the only flaw of the vehicle and they were wrong on charge port location. They did listen to the feedback. They have 2 years to fix it. https://t.co/d9mTqhBFWs— Chris Hilbert (@Hilbe) March 8, 2024
The Rivian R2’s charge port location has since become a well-discussed topic in social media. On Friday morning, Tesla Cybertruck Lead Engineer Wes Morrill weighed in on the matter, encouraging Rivian to move the charge port of the R2 to the rear driver’s side instead. While the Tesla Lead Engineer admitted that Tesla’s V4 Superchargers have longer cables that could accommodate electric vehicle charge port doors in any location, Tesla’s existing network of V3 and V2 Superchargers — which number over 50,000 — are optimized for vehicles whose charge port doors are located in the rear driver’s side.
“RJ Scaringe and Nick Kalayjian, cool product. Great looking prototypes. I know how these things go. There is still time to move the charge port location. It will take some re-engineering but the tools are not kicked off yet. This location will forever doom all Rivian owners to be the jerk taking two spots at a Tesla charger. Don’t do that to your customers.

“I know the Rivian Network has been installed to support the front left/rear right, but there are <500 Adventure Network fast charge handles vs more than 50,000 Supercharger handles. You’ve done the right thing for customers moving to NACS. Take it the last mile and put it in a location that works seamlessly with existing infrastructure. Can be the front right if you are trying to optimize for street parking. Looking forward to charging harmoniously with a great-looking EV,” Morrill wrote in a post on X.
Rivian has highlighted that it puts consumers’ feedback front and center when it designs its vehicles. Considering the substantial requests from EV community members calling for Rivian to move the location of the R2’s charge port door, it would truly be surprising if the electric vehicle maker stands firm and still releases the upcoming all-electric crossover SUV with its original charge port location.

Tesla has officially launched public Robotaxi rides in Austin, Texas, without a Safety Monitor in the vehicle, marking the first time the company has removed anyone from the vehicle other than the rider.
The Safety Monitor has been present in Tesla Robotaxis in Austin since its launch last June, maintaining safety for passengers and other vehicles, and was placed in the passenger’s seat.
Tesla planned to remove the Safety Monitor at the end of 2025, but it was not quite ready to do so. Now, in January, riders are officially reporting that they are able to hail a ride from a Model Y Robotaxi without anyone in the vehicle:

Tesla started testing this internally late last year and had several employees show that they were riding in the vehicle without anyone else there to intervene in case of an emergency.
Tesla has now expanded that program to the public, but it is currently unclear if that is the case across its entire fleet of vehicles in Austin at this point.
Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing
The Robotaxi program also operates in the California Bay Area, where the fleet is much larger, but Safety Monitors are placed in the driver’s seat and utilize Full Self-Driving, so it is essentially the same as an Uber driver using a Tesla with FSD.
In Austin, the removal of Safety Monitors marks a substantial achievement for Tesla moving forward. Now that it has enough confidence to remove Safety Monitors from Robotaxis altogether, there are nearly unlimited options for the company in terms of expansion.
While it is hoping to launch the ride-hailing service in more cities across the U.S. this year, this is a much larger development than expansion, at least for now, as it is the first time it is performing driverless rides in Robotaxi anywhere in the world for the public to enjoy.
Tesla has scheduled its Earnings Call for Q4 and Full Year 2025 for next Wednesday, January 28, at 5:30 p.m. EST, and investors are already preparing to get some answers from executives regarding a wide variety of topics.
The company accepts several questions from retail investors through the platform Say, which then allows shareholders to vote on the best questions.
Tesla does not answer anything regarding future product releases, but they are willing to shed light on current timelines, progress of certain projects, and other plans.
There are five questions that range over a variety of topics, including SpaceX, Full Self-Driving, Robotaxi, and Optimus, which are currently in the lead to be asked and potentially answered by Elon Musk and other Tesla executives:
- You once said: Loyalty deserves loyalty. Will long-term Tesla shareholders still be prioritized if SpaceX does an IPO?
- Our Take – With a lot of speculation regarding an incoming SpaceX IPO, Tesla investors, especially long-term ones, should be able to benefit from an early opportunity to purchase shares. This has been discussed endlessly over the past year, and we must be getting close to it.
- When is FSD going to be 100% unsupervised?
- Our Take – Musk said today that this is essentially a solved problem, and it could be available in the U.S. by the end of this year.
- What is the current bottleneck to increase Robotaxi deployment & personal use unsupervised FSD? The safety/performance of the most recent models or people to monitor robots, robotaxis, in-car, or remotely? Or something else?
- Our Take – The bottleneck seems to be based on data, which Musk said Tesla needs 10 billion miles of data to achieve unsupervised FSD. Once that happens, regulatory issues will be what hold things up from moving forward.
- Regarding Optimus, could you share the current number of units deployed in Tesla factories and actively performing production tasks? What specific roles or operations are they handling, and how has their integration impacted factory efficiency or output?
- Our Take – Optimus is going to have a larger role in factories moving forward, and later this year, they will have larger responsibilities.
- Can you please tie purchased FSD to our owner accounts vs. locked to the car? This will help us enjoy it in any Tesla we drive/buy and reward us for hanging in so long, some of us since 2017.
- Our Take – This is a good one and should get us some additional information on the FSD transfer plans and Subscription-only model that Tesla will adopt soon.
Tesla will have its Earnings Call on Wednesday, January 28.
Elon Musk shared an incredible detail about Tesla Cybercab’s potential efficiency, as the company has hinted in the past that it could be one of the most affordable vehicles to operate from a per-mile basis.
ARK Invest released a report recently that shed some light on the potential incremental cost per mile of various Robotaxis that will be available on the market in the coming years.
The Cybercab, which is detailed for the year 2030, has an exceptionally low cost of operation, which is something Tesla revealed when it unveiled the vehicle a year and a half ago at the “We, Robot” event in Los Angeles.
Musk said on numerous occasions that Tesla plans to hit the $0.20 cents per mile mark with the Cybercab, describing a “clear path” to achieving that figure and emphasizing it is the “full considered” cost, which would include energy, maintenance, cleaning, depreciation, and insurance.
Probably true
— Elon Musk (@elonmusk) January 22, 2026
ARK’s report showed that the Cybercab would be roughly half the cost of the Waymo 6th Gen Robotaxi in 2030, as that would come in at around $0.40 per mile all in. Cybercab, at scale, would be at $0.20.

This would be a dramatic decrease in the cost of operation for Tesla, and the savings would then be passed on to customers who choose to utilize the ride-sharing service for their own transportation needs.
The U.S. average cost of new vehicle ownership is about $0.77 per mile, according to AAA. Meanwhile, Uber and Lyft rideshares often cost between $1 and $4 per mile, while Waymo can cost between $0.60 and $1 or more per mile, according to some estimates.
Tesla’s engineering has been the true driver of these cost efficiencies, and its focus on creating a vehicle that is as cost-effective to operate as possible is truly going to pay off as the vehicle begins to scale. Tesla wants to get the Cybercab to about 5.5-6 miles per kWh, which has been discussed with prototypes.
Additionally, fewer parts due to the umboxed manufacturing process, a lower initial cost, and eliminating the need to pay humans for their labor would also contribute to a cheaper operational cost overall. While aspirational, all of the ingredients for this to be a real goal are there.
It may take some time as Tesla needs to hammer the manufacturing processes, and Musk has said there will be growing pains early. This week, he said regarding the early production efforts:
“…initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast.”
