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. 

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 revealed a major new Cybercab detail in a guide it released for First Responders, showing new territory in its beliefs and intentions for the ride-hailing-focused vehicle that entered production in April.

The First Responders Guide is released to give fire departments, paramedics, and other emergency personnel the proper guidance on what to do in the event of an accident, entrapment, or other situation that would require immediate attention.

On one of the pages of the First Responders Guide, Tesla revealed a stark detail about the Cybercab, which could help personnel enter the vehicle more easily in case of an emergency.

Tesla Cybercab has one important piece that AI4 cars might need for FSD

It shows Tesla has no intention of releasing any Cybercab units that were initially proposed for ride-hailing services for the general public with any manual controls, meaning a steering wheel or pedals:

“A Cybercab equipped with steering wheel, brake pedal, and an acceleration pedal is typically an engineering or test vehicle, and operates at SAE Level 2 autonomy. Cybercab is not typically equipped with a steering wheel or acceleration and brake pedals.”

This is a major development for those who continue to believe Tesla planned to release the Cybercab with any sort of manual controls so that passengers could take over if needed. However, when Tesla started manufacturing production versions of the Cybercab in Giga Texas earlier this year, they were spotted without a steering wheel or pedals.

It essentially confirms the company has no intentions of bringing manual controls to the car’s production versions. Some have argued that the likelihood of Tesla having something

There still are some Cybercab units out there with a steering wheel and pedals, and as Tesla said, these cars are engineering or test vehicles, which have Safety Monitors on board to help the car out of a precarious situation or emergency.

Tesla Full Self-Driving v14 ‘Lite’ Release Notes: new capabilities and features

Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.

Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.

Here are the full release notes for the suite:

  • Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
  • Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
  • Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
  • Introduced parking, unparking, and reversing capabilities.
  • Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
  • Speed Profiles are now available at all times, to further customize driving style preference.

These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.

Tesla Full Self-Driving v14 ‘Lite’ for older cars finally gets released

He added:

“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”

Tesla will continue to roll out the v14 Lite suite more widely in the coming weeks, the company said.

Tesla has finally released its Full Self-Driving v14 ‘Lite’ suite for older cars that equip the Hardware 3 or AI 3 chip, which have not been able to handle the newest versions of the company’s driver assistance software.

Tesla officially started releasing the v14 Lite suite to owners in the Early Access Program last night. The company’s Head of AI, Ashok Elluswamy, said that the rollout will continue over the next few weeks. The build distills the driving behavior from AI4’s v14 series into both the camera and compute configurations of an AI3 car.

It also includes a variety of new features that were available to AI4 cars running v14, including:

  • Start Self-Driving from Park
  • Arrival and Parking Options
  • Speed Profiles

The release is highly anticipated because those owners with AI3 vehicles were early adopters into the FSD platform and were promised that their cars would be capable of achieving Full Self-Driving.

However, Tesla CEO Elon Musk admitted during the company’s recent Q1 Earnings Call that these vehicles would not be capable of achieving unsupervised Full Self-Driving, which is what Tesla had originally said.

Owners were not pleased with this answer, or the idea that their commitment to buying the suite outright for thousands of dollars would not yield the ability to drive without operating the car. Tesla gave some solutions for this, including a discount on a new car, or an upgrade to an AI4 or AI5 self-driving computer and new, upgraded cameras.

Tesla owners do not seem pleased with these options, as they require giving the company more money.

Nevertheless, it is important to note that Tesla came through for owners here by releasing v14 Lite before the end of Q2, something it had promised owners during the previous Earnings Call. Tesla has had trouble keeping up with timelines, but this is a big achievement for the team.
