How will Tesla Version 8 compare to current Autopilot in the real world?

Tesla’s upcoming Version 8 software will be the company’s most significant Autopilot upgrade since its October 2014 initial release, but how will these updates compare to current Autopilot behavior in the real world?

This will be the first time the company will switch from using the vehicle’s front-facing camera as the core hardware responsible for visual image recognition, to radar technology which will now become the primary sensor used in creating a virtual picture of the vehicle’s surroundings.

With these improvements, to be rolled out via an over-the-air software update in the coming weeks, Model S equipped with the Autopilot hardware suite and Model X should theoretically be able to handle emergency braking situations with more precision, provide a smoother Traffic Aware Cruise Control (TACC) experience, take highway exits on its own, and provide drivers and passengers with an overall safer experience.

Let’s take a look at each of these features and see how Autopilot in Version 8 will differ from current Version 7 capabilities.

Automatic Emergency Braking

Following the much publicized death of Joshua Brown after his Model S crashed into the side of a tractor trailer while driving on Autopilot, reliability of Autopilot’s Automatic Emergency Braking (AEB) feature was immediately put to question. Tesla released a statement stating that the high, white side of the tractor trailer, combined with a radar signature that would have looked very similar to an overhead sign, caused automatic braking not to fire. “Since January 2016, Autopilot activates automatic emergency braking in response to any interruption of the ground plane in the path of the vehicle that cross-checks against a consistent radar signature,” said Tesla.

Spy shots taken from the Naval Air Station reveal Tesla was testing and calibrating its AEB system this past summer. But despite the tests which seemingly show a Model S automatically braking in a staged collision event, Tesla has been overly cautious when it comes to activation of its AEB feature. AEB is reliant on imagery received from its front-facing camera, and supplemented by radar input, to decide on the degree of confidence that would trigger a braking event.

Some Tesla owners have even taken it upon themselves to stage scenarios that would seemingly trigger the AEB response of the vehicle, but to no avail leaving further mystery as to how AEB works.

The current Autopilot system under Version 7 is limited in its ability to reliably detect people or pinpoint false positives such as reflective objects that may appear larger than they are. Tesla uses the concave bottom of a soda can as an example. When the radar signal is reflected back from the can’s bottom dish-shaped surface, the reflected signal is amplified to many times its actual size leading the radar to believe there’s a large object before it. Because of that, programming the AEB system to suddenly engage could lead to a dangerous situation so Tesla decided to limit the scenarios that could actually trigger an automatic emergency braking response.

However, Version 8 will combine the power of fleet learning with “radar snapshots” to improve the vehicle’s ability to more accurately depict the circumstances of an event. In other words, we can expect Autopilot under Version 8 to have a much higher degree of confidence when it comes to engaging automatic emergency braking. Tesla CEO Elon Musk believes this set up will provide safety improvements by a factor of three over existing Autopilot.

Traffic Aware Cruise Control

Beyond being able to track a vehicle that’s directly in front of the car, Version 8 of Autopilot will also be able to see the vehicle ahead of that. Tesla describes this update as follows: Tesla will also be able to bounce the radar signal under a vehicle in front – using the radar pulse signature and photon time of flight to distinguish the signal – and still brake even when trailing a car that is opaque to both vision and radar. The car in front might hit the UFO in dense fog, but the Tesla will not.

The improvement will lead to smoother braking events when TACC is engaged since Autopilot will no longer solely rely on the actions from the vehicle before it. If a hard braking event happened in front of the vehicle that Autopilot is immediately tracking, Version 8 will be able to identify it and slow the Model S (or Model X) even before the vehicle directly ahead may have applied the brakes.

The following video captures an incident whereby the vehicle being tracked by Version 7 of Autopilot could not see the hard braking event that took place two cars ahead. TACC seemingly did not have enough time to stop the Model S.

Being able to see two cars ahead in Version 8 will provide a smoother TACC experience and increased safety.

Improved Auto Lane Change and Freeway Exiting

What we’re particularly excited about is the new feature in Version 8.1 that will allow an Autopilot-equipped Model S and Model X to take highway exits using the onboard navigation system.

Currently, Version 7 of Autopilot is capable of handling lane changes when the driver explicitly uses the turn signal stalk. Signaling left and the vehicle will make a left lane change, and vice versa. However with the ability to punch in a destination through Tesla Nav and have the vehicle assist with freeway exiting, assuming that’s part of the route, in our minds, Tesla is taking a critical step towards the ultimate goal of building fully autonomous self-driving vehicles. It’s a small step, but nonetheless it’s a notable step.

Tesla Cybercab sightings on public roads are becoming more frequent

After it was unveiled a year ago by Tesla, the company has made some pretty drastic jumps in progress in terms of the Cybercab, but a recent development has truly pushed fans of the company to think it is probably going to be available soon.

Tesla Cybercab sightings on public roads are becoming much more frequent, and they all are pointing to one thing: imminent production.

The Tesla Cybercab is the company’s vehicle developed for fully autonomous travel, as it will be manufactured without a steering wheel or pedals, according to CEO Elon Musk.

Last week, we reported on the first Cybercab sighting when the vehicle was finally being tested on public roads. The spotting was not a one-time deal, as we are now seeing many more sightings on public roads:

The first spotting was in Palo Alto, just a few blocks from Tesla’s Engineering Headquarters in Los Altos. This second sighting appears to be relatively close to that first spotting, and it seems unlikely Tesla would be putting it on roads much further than that.

The public on-road testing of the Cybercab marks a major milestone in the entire project for Tesla. These early sightings and testing phases are usually followed by a lot of speculation about when the vehicle could end up in the hands of customers.

However, Tesla has already put a definitive date on when Cybercab production will begin, as Elon Musk said during the Q3 Earnings Call that it would roll off production lines in Q2 of next year.

But the speculation regarding the Cybercab is slightly different than other vehicles because Tesla has been developing it for fully autonomous travel; it’s not meant to be driven by humans but instead by software and the company’s Full Self-Driving suite.

Despite the vehicle being spotted with a steering wheel and pedals in the recent sightings, Musk has maintained that the Cybercab will not be developed with typical controls for a human. He recently confirmed this, and it does not seem the company is willing to veer too much from its plans for an autonomous car.

Tesla has rapidly progressed in the production of its most anticipated Model Y trim level: the Model Y Performance.

New drone images from noted drone operator and Gigafactory Texas observer Joe Tegtmeyer show Tesla is moving forward quickly in terms of its progress in producing the new Model Y Performance.

The vehicle is being spotted more frequently at the factory located just outside of Austin, with what appears to be the first units rolling out to outbound lots:

In the United States, Tesla unveiled the Model Y Performance on September 30, the newest iteration of the fastest trim level of the best-selling car in the world for the past two years. It was launched on the very last day of the $7,500 electric vehicle tax credit in the United States.

It featured a handful of performance improvements, including a 0-60 MPH acceleration rate of 3.3 seconds, a trim from the 3.5 seconds the 2025 version offered.

Additionally, the range has gone from 277 miles to 308 miles, a notable improvement in terms of how far it can travel on a charge.

There are also a handful of hardware changes that Tesla made to improve its aerodynamic performance, which all likely can be attributed to the boost in speed and acceleration, as well as range.

The vehicle was initially launched in Europe, which was not surprising, especially as Tesla was testing the new Performance trim at the famed Nurburgring in Germany.

Deliveries are currently slated for late November, but some orders are getting projections of mid-December for their Model Y Performance, which would help Tesla bolster its end-of-year delivery figures and follow up on an extremely bullish finish to Q3, which was the company’s strongest performance in history.

Twitter co-founder and Square CEO Jack Dorsey has publicly backed Elon Musk’s leadership ahead of Tesla’s pivotal shareholder vote, which is expected to be decided later today at the company’s 2025 annual meeting.

Dorsey framed the pay package as an engineering and governance crossroads for Tesla.

Dorsey’s public nod framed as an engineering defense of Musk

In a post on X, Dorsey weighed in on Tesla’s post about being in a “critical inflection point.” As per the Twitter-co-founder, the vote on Musk’s 2025 performance award is not about compensation. Instead, it’s about ensuring the path for the company’s engineering in the coming years.

“This is not about compensation. it’s about ensuring a principled (and exciting!) engineering approach to the company’s future,” Dorsey wrote on his post, later stating that users of Cash app with TSLA shares would be able to vote for the CEO’s proposed 2025 performance award.

Elon Musk appreciated Dorsey’s endorsement, responding to the Twitter co-founder’s post with a heart emoji. Musk has been pretty thankful for the support for is fellow tech executives, also thanking Michael Dell recently, who also advocated for its proposed 2025 performance award.

Musk’s support

While Elon Musk’s 2025 performance award has received opposition from proxy advisors such as Glass Lewis and ISS, it has received quite a lot of support from longtime bulls such as ARK Invest, and, more recently, Schwab Asset Management following calls from TSLA retail shareholders.

“Schwab Asset Management’s approach to voting on proxy matters is thorough and deliberate. We utilize a structured process that focuses on protecting and promoting shareholder value. We apply our own internal guidelines and do not rely on recommendations from Glass Lewis or ISS. In accordance with this process, Schwab Asset Management intends to vote in favor of the 2025 CEO performance award proposal. We firmly believe that supporting this proposal aligns both management and shareholder interests, ensuring the best outcome for all parties involved,” Charles Schwab told Teslarati.
