Tesla to Revive Low Regen Mode in Upcoming Update

Tesla appears ready to reintroduce a 'low' regenerative braking option

We reported last week that one of our users temporarily saw release notes for what appears to be an upcoming release in their Tesla app.

One of the features the user saw was an upcoming UI change to the Power Meter in the vehicle.

Another change the user saw was the reintroduction of low regen mode. The low regen mode makes it easier for drivers to adapt to the regenerative braking system (RBS) unique to electric and hybrid cars. However, it may result in reduced range and increased brake usage.

In the past, Tesla offered low and normal regen options, but newer models only featured the normal mode to encourage the more efficient option. With this update, it is expected that more recent models will now have the low regen mode available, giving drivers more control over their driving experience.

Activating and Monitoring Regen in a Tesla

Regenerative braking is a significant feature of electric vehicles, allowing drivers to slow down without using the brake pedal while recapturing energy and extending the life of braking components. This system can increase the range of the vehicle by up to 10 percent and extend the lifespan of braking mechanisms by more than 50 percent.

Tesla's regenerative braking system uses the electric motor to create resistance, slowing the vehicle down and capturing kinetic energy. This energy is then converted into electrical energy and fed back into the battery, increasing the vehicle's range. The regenerative braking system can be activated simply by lifting the foot off the accelerator, with the strength of the braking force and energy capture determined by the extent to which the accelerator is eased.

Brake Lights Activation During Regenerative Braking

During regenerative braking, Tesla vehicles ensure the activation of brake lights, even when the traditional brake pedal is not being used. The brake lights are turned on based on the vehicle's rate of deceleration. To check if your brake lights are on, you can look at the Tesla display screen, where the car illustration will show the brake lights as lit up when they are active. This feature ensures that other drivers know the Tesla vehicle's deceleration, improving overall road safety.

The reintroduction of the low regen mode offers drivers the opportunity to adjust to the unique braking experience of electric vehicles, gradually transitioning from traditional ICE vehicles. However, it is essential to note that using the low regen mode may result in reduced range and increased brake usage, making it a trade-off between driver comfort and overall efficiency.

Tesla Vehicles Spotted With LiDAR: What Do They Use It For?

Tesla recently hit the news for purchasing approximately $2M in LiDAR sensors from Luminar, one of Tesla’s long-term suppliers. You’ve probably seen photos of Tesla’s Semi and various Tesla models, including the Model 3 and Model Y sporting LIDAR equipment on the roof. These cars drive around with manufacturer plates scanning streets and highways.

However, many people confuse Tesla’s purpose in purchasing LiDAR equipment with using it for FSD versus testing. So, let’s look at what LiDAR is, and why Tesla uses it on its Fleet Validation Vehicles.

What is LiDAR?

LiDAR stands for Light Detecting and Ranging – essentially using lasers to measure distances. A laser pulse is sent out, and the time it takes to return is measured – providing extremely accurate distance measurements.

Some companies working on self-driving vehicles, including Waymo and BYD, use LiDAR as part of their self-driving suites, but Tesla is one of the few stand-outs that does not. Even Rimac’s “Verne” Robotaxi – which uses self-driving technology from Mobileye, also uses LiDAR.

While LiDAR can produce extremely accurate and high-quality 3D environments, it comes with its downsides as well. Not only is LiDAR costly and requires large gear strapped to a vehicle, but it also can not be used in bad weather and can have interference issues if there are other strong light sources present.

Why Does Tesla Use LiDAR?

At Autonomy Day in 2019, Elon Musk mentioned that LiDAR isn’t the solution for self-driving cars – it's just a crutch. Thus, Tesla hasn’t used LiDAR for any production self-driving software.

Instead, Tesla uses it exactly how it's described – they use it to gather ground-truth data. This data is then used to feed Tesla’s Full Self Driving system – which helps validate its vision-only system's accuracy. LiDAR provides very accurate measurements to help ensure that FSD’s perception of space is accurate – and is only used by Tesla to ensure that its AI technology which is the brains of FSD is capable of accurately interpreting depth from just visual data.

Tesla’s vision-only system has been seen to be extremely accurate, with Vision-only Autopark being able to park in even narrower and tighter spaces faster than the previous version that relied on ultrasonic sensors.

We’ll likely continue to see Tesla purchase LiDAR systems, as well as use them for validation well into the future.

Tesla's Upcoming Robotaxi Event in August Delayed, According to Bloomberg

In a report from Bloomberg, it is claimed that Tesla will be delaying its much-anticipated 8/8 Robotaxi event by two months to October 2024.

While sources other than Bloomberg haven't confirmed this report, Bloomberg has a positive track record of reporting on financial decisions. We’ll be sure to update the article if there is confirmation on X from Elon Musk or another Tesla senior official.

Tesla’s stock has dropped nearly 8.5% over the day, ending back-to-back gains over the last two weeks. It closed yesterday at $ 241 after hitting a peak of $270 earlier in the day before the news broke.

Why the Delay?

The delay – of approximately two months – has been communicated internally, but not publicly announced just yet. Bloomberg goes on to mention that the design team was told to rework certain elements of the Cybercab, necessitating the delay.

If Bloomberg’s report is correct, it sounds like Tesla’s unveil event will be largely focused on showing off the vehicle, instead of demoing how it will work. Of course, it could still be both, but given past events, Tesla has always shown off the vehicle years before it hits production.

Rimac recently showed off their version of robotaxi vehicle named Verne, and surprisingly, it could almost pass for Tesla’s own robotaxi. A lot of design cues in Rimac’s version are elements we have already seen or expect to see in Tesla’s autonomous taxi.

A recent Tesla patent revealed that Tesla is incorporating a sanitation system into their robotaxi that will be responsible for analyzing and cleaning the vehicle’s interior, although the delay itself is likely tied more to a physical feature rather than software.

Another element we know almost nothing about is how Tesla plans to charge these robotic taxis. Will they rely on the existing charge port and adapt a solution like the robotic charging arm (video below) we saw almost eight years ago, or will wireless charging or a dock finally become realized?

While the delay for Tesla’s event appears to be related to the vehicle’s design itself and not further development of FSD, Tesla is wasting no time in getting FSD working for the upcoming vehicle. Model 3 vehicles have already been spotted with camera locations that resemble a robotaxi.

Is the Delay Accurate?

We expect that this delay might actually be true – Elon Musk usually takes to X within hours of such news breaking if it's false to refute it and hasn’t done so yet.

Tesla has delayed several of their events in the past, and a delay of a couple of months seems plausible. We should hear from Musk himself soon on whether this report is accurate.
