Roundabouts aren’t always the easiest to navigate for human drivers, but one Tesla Model 3 was able to successfully go through one using its Smart Summon feature.

The host of YouTube channel All Electric wanted to see how his Model 3 would perform at navigating a roundabout using only Smart Summon. His Model 3, which had Tesla’s 2019.40.50.7 update installed, was able to make its way around the circular junction with minimum hiccups.

As the All Electric host pointed out, his Model 3 was able to enter the roundabout smoothly, while going at 5 mph and slowing down in some parts of the maneuver, before carefully exiting to reach its intended target location.

Tesla’s Smart Summon is a feature that allows users to remotely operate their Tesla from a parking spot to a designated location using their vehicles’ Full Self-Driving suite. The feature still requires users to be within 200 feet of their car, and uses the vehicles’ system of cameras, radar, and ultrasonic sensors to get around obstacles. Smart Summon is a step closer to Tesla CEO Elon Musk’s vision of deploying a fleet of autonomous vehicles.

Smart Summon has received plenty of improvements since it was released in September last year as part of the V10 update. The feature has also been put to the test many times, most recently proving that it can drive through a torrential downpour to rescue a family, navigate an intense obstacle course, and take its owner through a drive-thru restaurant.

With full backing from regulatory bodies, Tesla will likely be able to remove the 200-feet restriction on Smart Summon and allow users to call their cars from greater distances. CEO Elon Musk once even mentioned using Summon to call vehicles from across the country. Ultimately, Smart Summon may be a small feature for now, but it will play a central role in the deployment of self-driving Robotaxis.

Musk revealed further details for his vision of an autonomous ride-sharing program during Tesla’s Autonomy Day last year. Musk said he hoped to get the Tesla Network’s Robotaxi service running by 2020.

Elon Musk confirmed a future update will allow Tesla vehicles to create micro maps of roads that will help owners avoid potholes or other changes in the environment that are not available in conventional maps. The micro maps created from data collected by its fleet will be shared with fellow Tesla owners when they drive along the same road.

Reto Siegrist from Switzerland asked the Tesla CEO on Twitter about the possibility of adding the micro map feature to which Musk replied with a simple, “Yes.” Potholes can be big headaches for Tesla owners because they can cause serious accidents, damage tires and rims, which need repairs that can instantly burn through a few thousand dollars.

According to TRIP, a national transportation research non-profit group, about a third of major urban roads in the United States have pavements that are in substandard condition. Driving on such deteriorated roads cost motorists around $130 billion.

“Drivers are paying a hefty price for our nation’s crumbling roads and bridges. Those traveling daily through urban cities bear the weight of the problem – with many wasting thousands of dollars each year on rising transportation costs due to pot holes and wasted fuel,” said Kathleen Bower, AAA senior vice president of public affairs and international relations

Elon Musk has previously mentioned an anti-pothole feature that will allow Autopilot to safely avoid potholes without the need for driver input. This micro map shared among Tesla vehicles on the road will be a welcome addition to the anti-pothole feature.

Definitely

Detecting potholes can actually be challenging because unlike other obstacles, they are depressions on the road and may present differently depending on the current weather and lighting condition. In an ideal situation, the camera of Tesla’s electric car can determine a pothole by comparing the surface irregularity with the rest of the road and the texture inside the pothole compared to nearby pavement.

Tesla shared how its team is making progress in terms of developing its Full Self-Driving capabilities.

“…in terms of labeling, labeling with video in all eight cameras simultaneously. This is a really, I mean in terms of labeling efficiency, arguably like a three order of magnitude improvement in labeling efficiency,” Musk said.

The detection of potholes and the ability to seamlessly negotiate such obstacles on the road will be one big step for Tesla’s dream of having a fleet of truly autonomous cars. The ability of each car to share this information with other Teslas is also making most of the technology to make roads safer for everyone.

“Our networks learn from the most complicated and diverse scenarios in the world, iteratively sourced from our fleet of nearly 1M vehicles in real-time. A full build of Autopilot neural networks involves 48 networks that take 70,000 GPU hours to train. Together, they output 1,000 distinct tensors (predictions) at each timestep,” Tesla wrote to describe how its Autopilot neural networks work.

Elon Musk is also making sure that Tesla can accelerate further development of its FSD and Autopilot and will host an AI party at his house in a few weeks’ time. During the said event, Musk is hoping to find new talents to join Tesla and make functional applications out of the data available to the company.

Thanks to a recent cluster of major milestones, SpaceX’s family of Falcon 9 and Heavy rockets are rapidly nearing the halfway point along the path to several ambitious goals for booster and fairing reusability.

Back in the early 2010s, SpaceX’s CEO Elon Musk’s original dream was to make Falcon 9 and Falcon Heavy 100% reusable, meaning that the company would need to find ways to reliably recover boosters (first stages), payload fairings (or Dragon spacecraft), and the rocket’s upper (second) stages. The concept of Falcon 9 second stage reuse actually survived all the way into 2018 before Musk ultimately conceded defeat, accepting that Falcon 9 and Heavy simply didn’t offer the performance necessary to make full reusability a worthwhile investment. The concept, however, still lives on in SpaceX’s next-generation Starship launch vehicle.

This does mean Falcon rockets will never be fully reusable, but it’s still up to SpaceX to decide how far they’ll push the envelope with the rockets’ existing reusable hardware. At the moment, it appears that a vast majority of Falcon rockets will be able to be routinely recovered and reused, capitalizing on the fact that Falcon 9 and Falcon Heavy boosters already represent some 50-75% of the cost of building each two-stage rocket. While Falcon upper stages and Dragon trunks will never be reused, both booster and payload fairing reuse are rapidly approaching their own unique halfway points on the path to ambitious reusability targets.

Shortly after SpaceX’s January 29th Starlink V1 L3 launch, carrying the third batch of 60 upgraded v1.0 satellites to orbit, twin fairing recovery ships GO Ms. Tree (formerly Mr. Steven) and Ms. Chief teamed up for their second-ever simultaneous fairing catch attempt. Ms. Chief – only active since November 2019 – reportedly just barely missed her first successful catch, while Ms. Tree managed to snag one of the Falcon 9 fairing halves in her massive net – the ship’s third successful catch.

Worth an estimated $3M per half according to CEO Elon Musk, Falcon 9’s payload fairing represents approximately 10% of the rocket’s total manufacturing cost. Made out of a carbon fiber and aluminum honeycomb composite material, fairings also also takes a disproportionate amount of time and space to produce – primarily due to their large size (a school bus could comfortably fit inside a fairing) and the need for commensurately large curing ovens. That composite honeycomb structure also makes it relatively easy for Falcon payload fairings to suffer from corrosion when dunked in seawater, leading SpaceX to the seemingly bizarre solution of installing giant arms and nets on ships.

Catching fairings has proven to be incredibly unforgiving, however, and SpaceX has simultaneously worked to make its Falcon fairings much more waterproof (and thus resistant to corrosion) while keeping them as light as possible. In fact, SpaceX’s first fairing reuse occurred less than three months ago and used two halves that previously landed in the Atlantic Ocean, demonstrating that difficulties reliably catching fairings will not stand in the way of reuse.

Ms. Chief missed her January 29th catch attempt, she still managed to fish her fairing half out of the ocean, while Ms. Tree’s successfully-caught half means that SpaceX ultimately recovered the full Starlink V1 L3 fairing. With a little luck, that recovered fairing will launch again in the near future.

Five for 5

Simultaneously, SpaceX is making excellent progress along the path to airliner-like rocket reusability. In November 2019, on the same Starlink mission that debuted flight-proven fairings, Falcon 9 booster B1048 became the first SpaceX rocket to launch (and land) four times. Less than two months later, Falcon 9 B1049 doubled down on that reusability milestone, becoming the second booster to launch and land four times, followed by Falcon 9 B1046 just 12 days later. Falcon 9 B1046 was (intentionally) destroyed after its fourth launch, precluding a fourth landing attempt, but it emphasizes just how confident SpaceX is in Falcon 9’s Block 5 upgrade.

Designed to allow each Falcon 9 and Heavy booster to perform a minimum of 10 launches and landings, the Block 5 upgrade is potentially just a few weeks away from reaching the halfway point along the path to that ambitious reusability design goal. Speaking at the NASA Kennedy Space Center earlier this month, a SpaceX engineer recently revealed that a Falcon 9 booster would conduct its fifth launch in support of a Starlink mission (either Starlink V1 L4 or L5) scheduled no earlier than (NET) mid-to-late February.

Pictured above, Falcon 9 booster B1048 – the first to launch four times – is the likeliest candidate for the first fifth flight of a SpaceX rocket. If the booster’s reuse goes as planned, it’s safe to say that Falcon 9 B1049.4 will follow closely on the heels of its predecessor with its own fifth-flight milestone. All things considered, SpaceX’s workhorse rocket is rapidly approaching the zenith of its theoretically-achievable reusability.

A Tesla Model Y Performance prototype with white seats was spotted in a Los Angeles parking garage over the weekend.

All sightings of Tesla’s upcoming all-electric crossover thus far have been with the standard black interior. This most recent sighting gives Model Y pre-order reservation holders a first-hand look of how the vehicle may appear with Tesla’s all-vegan white interior.

In the series of photos posted on the r/TeslaMotors subreddit by u/lastnamethai, the Model Y appears production-ready and with subtle modifications to its body style since the vehicle was first spotted outside of the company’s factory in Fremont, California last year.

The newest Model Y sighting joins numerous other sightings that have taken place on public roads across the US, and another on Tesla’s factory test track. In some instances, test vehicles have been outfitted with calibration instruments.

In Tesla’s Q4 2019 earnings update, the company credits Model 3 production improvements for helping fine-tune the production of the Model Y. The two vehicles share nearly 75% of the same parts, making for an easier transition to Model Y production which began in Fremont earlier this year.

The Model Y has also received benefits from Tesla’s continually improving engineering processes. The company announced that the EPA upgraded its range on its AWD variants of the vehicle from 280 to 315 miles. “This extends Model Y’s lead as the most energy-efficient electric SUV in the world,” the company stated.

As of now, the Model Y is available for purchase in two variants. The Long Range Dual Motor and Performance variants will both have an EPA-rated range of 315 miles and cost $52,990, and $60,990 respectively. Tesla Model Y first deliveries will begin by the end of Q1 2020.
