While unprotected left turns can be nerve-wracking for novice drivers, many FSD Beta participants still experience anxiety when their car is faced with such a turn.
Unprotected left turns are one of the harder driving maneuvers to make for humans and AI, as they leave your vehicle vulnerable while turning (instead of turning with traffic).
Tesla quickly recognized the difficulties their AI was experiencing in safely executing these turns and has been working diligently to improve the AI’s ability to discern oncoming hazards.
Solve Chazman's Complicated Left Turns
FSD Beta 10.12 improved unprotected left turn issues, but there are still some lingering issues.
Chuck Cook (@Chazman) has been iteratively testing FSD Beta's ability to make unprotected left turns on a busy route.
It's a complicated turn that involved crossing three lanes of traffic before reaching the median and then turning left.
Often it involves crossing the three lanes and waiting at the median before finding enough clearance to get into a lane.
It's complicated, even for humans. However, Elon Musk said in a recent tweet that beta 10.13 would solve Chuck's complicated left turns 'most of the time.'

Smoother Intersections
Elon also added that 10.13 would "smooth out intersection control," hopefully reducing the vehicle's hesitation and steering jerkiness that can happen in busy intersections.
Going Deep on Roundabouts
In addition to unprotected left turns, traffic circle/roundabout navigation has become a focus of FSD engineers.
While popular abroad, roundabouts are seldomly used in the US. Although there are estimated to be 2600+ roundabouts across the country, so FSD Beta needs to be able to handle them well.
FSD Beta's navigation of roundabouts has been spotty, although one could argue that multi-lane roundabouts are challenging even for experienced drivers.
With FSD Beta 10.13, Musk says that Tesla is going 'deep on roundabouts,' and that it should be noticeably better in that iteration of FSD Beta.
There are certainly some complicated roundabouts out there that can challenge even the most skilled drivers. Some roundabouts include multiple lanes and may require you to change lanes within the roundabout, some may even include roundabouts leading into or out of the roundabout, such as the 'Magic Roundabout' in Swindon, England.

Navigate without Map Data
Musk also hinted at another major improvement that may be included in 10.13: the ability for FSD beta to navigate roads with no map data.
The vehicle will be able to navigate to a specific GPS point or pinned location (ex: rural roads), says Musk.
Dead Reckoning Navigation (Navigating without GPS)
In addition, Elon alluded to the fact that Tesla is also working on the AI’s ability to complete 'dead reckoning' navigation (navigating only on “inertial measurements, wheel movement & vision”).
He gave underground parking garages as an example of where FSD would need this ability to navigate without GPS or map data.
The car will be able to do this by using its last known GPS location and then determining its future location using only a compass, wheel movement and speed.
Yes, car will navigate to a pin location, even if in a complex surface parking lot or hotel entrance.
When in covered or underground parking lots, car will have to navigate using only inertial measurement, wheel movement & vision, as GPS signal is no longer available.
Elon said that he expects FSD Beta 10.13 to be available in about two weeks.
Why is it always two weeks? Tesla may use an agile approach to software development. In agile development work is planned in 'sprints' that span one or more weeks, with two weeks being a common length.
It's possible Tesla uses two-week sprints when planning and developing upcoming features.
For drivers that have experienced the intense nature of FSD left turns through busy intersections, it looks like they won’t have to wait long for FSD Beta 10.13.

Back in 2023, Tesla put together a rather unique Supercharger site idea - one with a CyberCanopy. This canopy is intended to provide solar power for Supercharging, helping to reduce the impact on the local grid while also providing a futuristic and Cybertruck-themed location that would set it apart.
Unfortunately, the plans never moved beyond the filing stage. Instead, Tesla opened a standard-looking Supercharger at the same Canton, Massachusetts location. However, the site is still well-situated just off the highway and benefits from natural tree cover in the parking area.
However, Tesla is at it again with a concept for another CyberCanopy with RGB lighting. Thanks to MarkoRP for spotting this. No April Fool’s this time.
We want to build a few Superchargers cool enough to be worthy of the trip itself. - Max de Zegher
CyberCanopy 2
This second Supercharger with CyberCanopy is set for Roswell, New Mexico, at the Whataburger in town. Featuring just eight stalls, this will be one of Tesla’s smaller Supercharger sites, but for what it lacks in size, it makes up for it in uniqueness. The charging stalls are covered from the rain by a futuristic, Cybertruck-themed canopy, which will have solar panels installed on the top of it.
According to the plans, the CyberCanopy boasts 20.88kW of solar panels on its roof, providing shelter from the elements while also providing some power back to the grid.
RGB Lighting
At nighttime, the Supercharger will make a big statement. Tesla intends to light the long edges of the canopy, which will not only look amazing, but it’ll actually make finding the Supercharger easier in a large parking lot.
The lighting coming off the edge of the canopy reminds us a lot of the lightbar on the Cybertruck and now the new Model Y. It’s definitely the direction Tesla is moving for all their models, so expect all future models to have it, including the new Roadster and the next-gen model.
Tesla’s Max de Zegher also took to X after the plans for the new Supercharger were found and shared the image above. He stated that Tesla wants to build a few cool Superchargers that will be worth stopping at, even if they’re out of the way a little bit. So it seems like this isn’t just a concept, but an idea that Tesla wants to expand to several areas around the country or world.
We want to build a few Superchargers cool enough to be worthy of the trip itself. Wish we could have kept it under wraps for longer, but submittal was needed for Planning Approval. We can't hide anything from @MarcoRPi1! 🙂 pic.twitter.com/X2WaKDd408
This particular site doesn't have a Megapack or other form of energy storage, unlike the upcoming Harris Ranch Supercharger site in California. That means that Tesla won’t be storing the solar energy gained from this site, but instead will be either offsetting the immediate grid impact or serving energy back to the grid when the site isn’t actively charging.
Tesla will likely be incorporating V4 Superchargers, including both V4 posts and the new, more powerful V4 Cabinets, as the permit states that Tesla will be redesigning the site internally before beginning construction. For Cybertruck owners, 500kW charging may be around the corner.
We’re hoping Tesla continues to deploy these kinds of Supercharger sites around the world - they make a stylistic statement about Tesla’s futurism, like the Shell gas station that was upcycled into a Supercharger site earlier this year in Spain.
They also make a big impact for ownership because it is a far more comfortable charging experience when you stop at a site that’s shaded from the elements - and one that’s better for the environment with offset emissions.
It was a rainy April 1st when a news-searching author went on a delve into the depths of April Fools to find fact from falsehood. And while we found a lot of fantastic jokes, we also found some good ideas.
So, with a shoutout to MarcoRP on X, whose April Fool’s Joke gave us a good run for our money for a couple of minutes, we thought to ourselves - what would a Cybercab Charging Station / Cleaning Hub really look like?
Cybercab Wireless Charging Sites
Now, before continuing, we’d like to point out that the image up top is a joke from Marco - it isn’t an accurate or real site map submission from Tesla. However, it gave us the impetus to think critically about what is required for a Robotaxi fleet, based primarily on the Cybercab, to be able to service a city.
Requirements
Tesla will likely need to charge a small fleet of Cybercabs at a single time and in a single place. That means that the site needs to be large enough to cover a major metro area while also still being compact enough to not cost too much money to build out.
In addition, we need to factor in charge times. The Cybercab is likely to launch with a battery around 50 kWh, which will result in a range of approximately 300 miles. With that much range, the average Cybercab may not need to charge more than once or at all during daytime shifts, so instead, most of the vehicles will charge overnight.
MarcoRP
Math and Charge Times
The overnight charging means that most of these vehicles could be charged slowly. When we did some back-of-the-napkin math last year, we determined that Tesla’s wireless charger will likely peak around 17 kW (for comparison, Tesla’s Wall Connector at 32 amps charges at about 7 kW). If we scale Tesla’s wireless charger down slightly to 10 kW, accounting for some energy loss and the potential size of the site, that means a Cybercab will be able to charge in about 5 hours.
Tesla’s upcoming V4 Supercharger unit can currently handle 1.5MW per cabinet, but this slower-speed charging is A/C, not DC, which means there is a step-down loss of about 3-5%. Let’s make that a comfortable 10% for any other overages, but we can estimate around 1.35MW of power. That 1.3MW will easily handle charging up to 100 Cybercabs at once - all wirelessly, using Tesla’s unique beam-forming and beam-steering technology to keep efficiency high at every single stall.
Within about 5 hours, a whole fleet of 100 Cybercabs could be charged overnight when electricity rates are cheaper and still be out in time for the morning commute.
While this is all just hypothetical, it really does make sense that Tesla will be establishing these sites that won’t require much space or a ton of energy.
Tesla recently curtained off a large section of the parking garage at Giga Texas, as well as some of their chargers on the eastern end of the facility, leading us to believe they may just be testing this at scale internally.
There’s a lot to look forward to with Tesla’s V4 Supercharger deployment coming this year and with Robotaxi launching in just a couple of months.
