Robotaxis

Elon Musk claims Tesla will have 1 million robotaxis on roads next year. Currently, Tesla offers Autopilot – an advanced driver assistance system – as a standard feature in its cars. According to the company’s website, Autopilot can automatically hold a car in its lane and accelerate or brake robotically, for example, in response to pedestrians or other cars in its way. Tesla can improve Autopilot with new features (or bug fixes) over time via over-the-air updates, as well. In addition, Tesla sells a “Full Self-Driving,” or FSD, package for its vehicles.

Some would say that Tesla is years ahead of the competition when it comes to powertrain efficiency and software. Since October of 2016, all Tesla’s sold are “capable of full autonomy” pending software and an updated processor released this year. Each Tesla has 360-degree vision from 8 cameras, 12 ultrasonic sensors, and a forward-looking radar.

Despite the equipment that comes with a Tesla there are people who believes Tesla’s vision-based autonomy strategy will not work with existing computer vision and AI. Sean Chandler from Seeking Alpa don’t think it will be reliable enough for regulatory approval.   

Sean thinks it is clear that in the long run, a vision-based autonomous car is the most cost-effective way to go. Humans drive with just two eyes; Tesla has 8 eyes, 12 ultrasonic sensors, and a forward radar. However, humans have deep understandings of the roads that we drive and the things that we see. Having more eyes and sensors means that the car doesn’t have to be as smart as a human, but it still needs to be very smart. He would argue that Tesla has yet to prove that they can do autonomy across a variety of scenarios.

Earlier this year during a podcast with ARK Invest, Elon Musk said that the cars would soon be feature complete, or level 3/4 on the scale below.

Here’s what Elon Musk said during the podcast:

I think we will be feature complete full self driving this year. Meaning the car will be able to find you in a parking lot, pick you up, take you all the way to your destination without an intervention. This year. I would say that I am certain of that; that is not a question mark.

Surprisingly, on Tesla’s recent earnings call he confirmed that it’s still possible that something will be out this year:

  • “While it’s going to be tight, it still does appear that there will be at least an early access release of a feature-complete full self-driving feature this year. So it’s not for sure, but it appears to be on track for at least an early access release of a fully functional Full Self-Driving by the end of this year.”

With the exception of a demo in 2016 and a demo for investors earlier this year at Autonomy Day, customers and investors have no idea what to expect. (Videos to demos: 2016, 2019). Some positives we have seen though is substantial improvements to Autopilot and Navigate on Autopilot, which is the best level 2 system on the market.

However, unlike companies like Waymo (GOOG) (NASDAQ:GOOG) or Zoox that are constantly releasing footage of what their vehicles are capable of – Tesla doesn’t release anything.

Here’s videos of a Waymo car navigating a dust storm and a police-controlled intersection. Zoox has videos of its cars navigating San Francisco and Las Vegas, such as passing double-parked cars and yielding to dozens of pedestrians.

Recent updates to Autopilot have shown that it can detect stoplights, stop signs, and cones. Tesla’s Autopilot driver-assist features appears to be more advanced than any other production car available to consumers.

Tesla justified the latest price hike to its Full Self-Driving option with the release of Smart Summon, which was released days before Q3 ended, allowing Tesla to recognize $30M worth of Full Self-Driving revenue on its quarterly report.

Sean thinks the Smart Summon is great and appears to work most of the time but it’s far from perfect. Parking lots are chaotic and happen to be an entirely new driving category for Tesla.

Last month, Scott Kubo released a video of his Model 3 heading straight towards a movable barrier on Coronado Bridge in San Diego. This happened to be an extremely rare situation.

The concrete barrier is moved twice per day to regulate traffic flow between San Diego and Coronado Island. The driver was heading towards Coronado Island at approximately 5:40PM during sunset, likely before or while the barrier was being moved back (usually starts around 5:30).

Like Scott said in his video, the sun was setting and the barrier on the right was casting a long shadow across the road and part of the movable barrier on the left. Only a tiny part of the barrier was in direct sunlight.

The perfect size of the reflection looks very much like a lane marking and the point in which the barrier meets the road is actually quite subtle.

The Autopilot system, which is constantly searching for lane markings, likely identified the reflection of the sun as a lane marking and misidentified the barrier as part of the road.

With computer vision, a big problem with roads is that they can vary in shades of gray. Some sections can be concrete (light gray) asphalt (dark gray) and some road sections may be newer (darker).

When Smart Summon was delayed, Elon Musk said that they were obsessed with curbs and that the hardest part about concrete is the excessive shades of gray. Throw in shadows, which can be at varying angles and intensities throughout the day/year and this becomes even more difficult for a vision-only system.

The situation Scott came across is so rare that just replicating the conditions would be difficult. During the summer, when the sun sets much later (long after the barrier is moved), these conditions aren’t possible. And due to the thickness of the shadow, this event can only happen for just a few minutes each day.

This is one of those scenarios where engineers are chasing the 9s to make the system 99.9999-something percent accurate.

On the plus side, Tesla’s large fleet gets to encounter and discover unique situations like this that most likely wouldn’t occur in a simulation.

On the flip side though, it raises questions about autonomy under Tesla’s strategy that relies primarily on vision. The system also uses ultrasonics and a front radar, but I’m not sure what happened in this case.

While there are many ways that this situation could have been prevented (such as reading and understanding the flashing “Merge Right” sign, or the traditional merge sign), it goes to show that the system needs a lot of work.

In this case, a redundancy such as LiDAR would have been an easy way to identify the barrier.

When it comes to LiDAR, Elon Musk calls it “lame”, or more specifically an expensive “crutch” when it comes to self-driving cars. He’s not wrong. LiDAR is expensive and once computer vision is mastered it may not be necessary. However, the question remains as to how long will it take for computer vision to be mastered. Zoox CTO Jesse Levinson said it could be decades. That’s quite far off, but even if it took 3-5 years that could be devastating, at least if the competition figures it out first.

In suburban Phoenix, Waymo is operating a fleet of self-driving cars and some of those cars are no longer using safety drivers. If Waymo can successfully deploy a large fleet of fully autonomous vehicles in this test area, their efforts will likely be accelerated across the globe. Mastering a single location would likely reduce complications with regulators; in fact, if Waymo is successful in one city, regulators in other cities may be asking Waymo to be in the next city on the list.

Who will win the race?

General Motors is putting down enormous, simultaneous stakes on electric cars and self-driving technology, a strategic bet based on its confidence that future automated vehicles will run only on electricity.

It’s a risky bet, especially if EVs and AVs are slow to be recognized by consumers. Other carmakers, like Ford, see near-term limitations to battery-electric AVs and favor a more measured method.

General Motors trusts both technologies are approaching a tipping point and hopes they will push it to the forefront of an enormous industry shift toward shared, self-driving electric cars.

“The only way to lead in either one is to go heavy and hard in both of them,” said Doug Parks, GM VP for autonomous and electric vehicle programs.

Automakers are split on the path to electrification, the Wall Street Journal reports.

  • Toyota and Ford are rolling out more hybrid gas-electric models as part of a gradual shift toward fully electric cars. They are both heavily invested in hybrid tech.
  • GM and Volkswagen see no need for hybrids as a technology bridge and are concentrating instead on all-electric models. They also need to defend their strong positions in China, where they face government mandates to sell more zero-emissions vehicles.

The companies’ views on self-driving technology also influence their plans toward electrification.

GM says all-electric autonomous cars have an advantage over hybrid- and gasoline-powered ones.

  • They’re ideal for dense cities that need solutions for congestion and pollution.
  • AVs require a lot of electrical power to run their advanced sensing and computer hardware.
  • An all-electric AV is more responsive so it can make decisions and complete maneuvers like navigating around a double-parked car more quickly.

Ford sees real-world issues that favor hybrid powertrains for AVs for the time being.

  • Building the necessary charging infrastructure will add to the already capital-intensive challenge of developing AV technology and operations.
  • Until battery technology improves, an AV’s power-hungry computers (along with air conditioning and entertainment systems) will deplete more than half the range of a battery-electric vehicle.
  • If cars are sitting on chargers, they aren’t making money. 
  • Fast-charging is needed to run an AV fleet, but Ford says repeated use will degrade the battery’s lifespan. (GM says this isn’t a concern.)

“We all want to transition to BEVs eventually, but we also need to find the right balance that will help develop a profitable, viable business model,” said Sherif Marakby, president and CEO of Ford Autonomous Vehicles LLC.

Uber and drone deliveries

The ride-sharing provider Uber is creeping further into daily life, with ambitions to help manage everything from how people get to work to what meals they order when they get home.

At a conference this week Uber was showcasing concepts and partnerships as it tries to seed an ecosystem to support the world’s first urban air taxi network.

Speaking Tuesday to an audience at the Economic Club of Washington, D.C., Uber CEO Dara Khosrowshahi said…

  • “We really want to move from being a ride-hailing app to essentially being your transportation partner.”
  • His vision is to have a multi-modal Uber transportation network that, with a push of a button, helps people plan how to get from A to B, balancing tradeoffs like time, convenience and price.
  • Uber doesn’t just want to move people — this morning, the company announced it will start testing drone food delivery in urban areas.

Serious obstacles stand in the way of flying cars, including regulations, infrastructure and air traffic management issues, not to mention consumer acceptance and safety, Deloitte’s Robin Lineberger tells Axios.

  • “They will be a legitimate part of a multi-modal transportation system, in 20 to 30 years,” he says.

At its third annual Uber Elevate conference, the company showcased vertical takeoff and landing models from 5 potential suppliers, including a full-size model from Bell that looks like a cross between a plane and a helicopter.

  • Attendees could climb into a mockup of a cabin interior built by the French aerospace company Safran or strap on virtual reality headsets to experience what a flying taxi ride would be like.
  • Uber said Melbourne, Australia, would be its first international pilot site for Uber Air, after Los Angeles and Dallas-Fort Worth in the United States, starting in 2020.
  • And it showcased 16 potential designs for urban skyports, where flying taxis would take off and land.

Uber wants to “get the industry moving and designing these vehicles so that they can be available for urban transportation,” Khosrowshahi said. “We want the pricing of this service to be ultimately available for the masses versus just the elites.”

So far, it looks out of reach for most. A new 8-minute Uber helicopter shuttle between Manhattan and John F. Kennedy Airport is expected to cost $200 when it launches next month.

  • In the wake of a helicopter crash this week on the roof of a building in Manhattan, some lawmakers want to see a ban on such flights.
  • And some argue it overshadows existing transit reform efforts.

The bottom line: The market for air taxis is expected to grow from $3.4 billion in 2025 to $17.7 billion by 2040, according to Deloitte, and for newly public Uber, which lost $1 billion in the first quarter of 2019, that opportunity is hard to pass up.

  • “We think it’s time to lean forward,” Khosrowshahi says. “The business is well positioned to profit. But the next 2, 3, 4 years are going to be about growth.”

Real world testing to L4

This is an article written by Michael DeKort “Today I see VW switched from Aurora to Argo. That switch will not matter in the least. As a matter of fact, you could literally combine every Autonomous Vehicle maker together and you will still never get remotely close to a legitimate L4. The use of public shadow and safety driving as well as gaming engines for simulation are that debilitating.

Public Shadow and Safety Driving — There is no way to mitigate the amount of time/work/miles (500B per RAND — One Trillion per Toyota) by driving and redriving scenarios you would have to stumble and restumble on. Spend the associated amount of money (+$300B). Or survive the casualties that will be created when handover is involved in time critical scenarios or when thousands of accident scenarios are run thousands of times each to train the ML.

Gaming Engine based Simulation — With regard to gaming engines. The real-time and model fidelity issues those systems cause especially in complex scenarios will cause differences between what the Planning system believes will occur and what will actually occur in analogous real-world scenarios. That will provide significant false confidence and lead to tragedies.

The Solution — The remedy is to use aerospace/DoD/FAA simulation technology and systems/safety engineering. Including augmenting that bottoms up Agile approach with a parallel top down approach. We also have a built in RL Engine automatic training capability built into the simulation. I will be glad to provide a demonstration this is the right approach. (Note- When I mention this approach folks usually think I am referring to air travel which is not nearly as complex as what is needed here. What is as complex and even more so is simulated DoD urban war games. Same locations, same complexity and the public experiences plus the ground vehicles can drive off the roads and shoot at each other.)

Update 6–12–2019 — Far worse than I stated

Over 1,400 self-driving vehicles are now in testing by 80+ companies across the US

Let’s look at the math on this compared to RAND’s estimate that it would take 500B to get to 10X a human and Toyota’s 1 trillion miles. At 40MPH driven 24X7 how long would it take to get to L4?

RAND 500B miles = 1019 Years

Toyota’s One Trillion miles = 2038 Years

1/10 of RAND’s estimated miles = 102 years

We’re driving computers.

Cars of the future need to be able to heal themselves. We’re not driving cars anymore — we’re driving computers.

Cars are complicated, with 100 or more computer-controlled subsystems that are needed for functions like steering, braking, and adjusting the seats. And all that hardware is embedded with massive amounts of software.

  • By 2020, 98% of new cars will be connected to the internet, making it easier to add new features or capabilities via over-the-air software updates.
  • Samsung’s Harman subsidiary handles OTA updates for 24 automakers, but most carmakers still require customers to make a trip to the dealership for driving updates.
  • Tesla is the exception. The company says it has pushed out hundreds of OTA updates to its vehicles since 2012.

Being connected to the internet can make vehicles vulnerable and software updates can sometimes introduce new problems.

The risks will only grow in the push toward automation, so having a software safety net will be important, tech analysts say.

  • “It’s going to be a necessity — especially when you’re downloading safety critical systems — that you don’t break the car,” says Michael Ramsey, mobility analyst at Gartner.

What to watch: New self-healing software from Israeli startup Aurora Labs — now undergoing tests by a half-dozen automakers — monitors a car’s systems to help ensure that doesn’t happen.

  • It uses artificial intelligence to self-diagnose coding problems and fix errors on-the-go.
  • The technology sifts line-by-line through the estimated 100 million lines of code in today’s cars to detect faults and predict problems before they occur.
  • If it finds a glitch, the software seamlessly rolls back to an earlier, safer version so related functions aren’t disabled while the problem is addressed. (Harman says it, too, has rollback capability.)
  • Self-healing software could be a viable way to protect against both malicious and accidental corruption of vehicle software, Navigant Research analyst Sam Abuelsamid says.

Yes, but: The approach requires additional onboard storage to preserve all of the previous changes, which could bog down performance. New electronic systems that automakers have in the works should address that, Abuelsamid notes.

The bottom line: If machines are going to replace human drivers, they will need to be resilient like humans.

First AV EV Truck….

15th May was a historic occasion. The first cab-less, electric truck – Einride’s T-pod – drove on a public road. The world premiere and inaugural run took place at DB Schenker’s facility in Jönköping, Sweden. The T-pod will transport goods between a warehouse and terminal at the facility, as part of a commercial flow.

Robert Falck, founder and CEO of Einride, Jochen Thewes, CEO of DB Schenker, and Mats Grundius, CEO of DB Schenker Cluster Sweden, Denmark, Iceland hosted the inauguration ceremony.

– This day represents a major milestone in Einride’s history, and for our movement to create a safe, efficient and sustainable transport solution, based on autonomous, electric vehicles, that has the potential to reduce CO2 emissions from road freight transport by up to 90 percent. I can’t begin to describe how proud I am of our team that made this happen in collaboration with our great partner and customer DB Schenker, says Robert Falck, CEO and founder of Einride.

– Autonomous trucks will become increasingly important for the logistics sector. Together with Einride, we have now introduced autonomous, fully electric trucks to a continuous flow on a public road – a milestone in the transition to the transport system of tomorrow,” said Jochen Thewes, CEO of DB Schenker.

In November 2018, the Swedish startup Einride and leading logistics firm DB Schenker initiated the first installation of an autonomous, all-electric truck or “T-pod” at a DB Schenker facility in Jönköping, Sweden. It was the first commercial installation of its kind in the world.

March 7 the Swedish Transport Agency concluded that the T-pod is able to operate in accordance with Swedish traffic regulations. March 11, the agency approved Einride’s application to expand the pilot to a public road. The permit applies to a public road within an industrial area – between a warehouse and a terminal. The permit is valid until December 31, 2020.

Einride and DB Schenker entered into a commercial agreement in April 2018 that includes the pilot in Jönköping and an option for additional pilots internationally.

Elon Musk and SpaceX

Elon Musk believes he could make a journey to Mars just seven years from now. He recently claimed there is a 70% likelihood he will make it to Mars on one of his spacecrafts. Even if it means “a good chance of death” Elon told Axios on HBO [1].

Elon Reeve Musk is a technology entrepreneur and engineer. Born and raised in South Africa, Musk moved to Canada when he was 17 to attend Queen’s University. Two years later, he transferred to the University of Pennsylvania, where he received an economics degree from the Wharton School and a degree in physics from the College of Arts and Sciences. A few years later he began a Ph.D. in applied physics and material sciences at Stanford University but dropped out after two days to pursue an entrepreneurial career.

After dropping of school he co-founded Zip2, which was acquired by Compaq for $340 millions in 1999. He then founded an online bank called x.com, which later merged with Confinity in 2000 and became PayPal. Elon is the co-founder of Neuralink, a neurotechnology company focused on developing brain computer interfaces, and he also co-founded OpenAI, a nonprofit research company that aims to promote friendly artificial intelligence.

Elon helped to fund Tesla and became their CEO in 2003 where he inspired the creation of SolarCity, a solar energy services company that is a subsidiary of Tesla. He is also founder of The Boring Company, an infrastructure and tunnel-construction company. Last but not least he founded SpaceX, an aerospace manufacturer and space transport services company.

Musk has stated that his goals of SpaceX, Tesla, and SolarCity revolve around his vision to change the world and it include reducing global warming, and reducing the risk of human extinction by establishing a human colony on Mars [2].

To be able to bring people to Mars, SpaceX has developed Falcon 9, a two-stage rocket designed and manufactured to transport satellites and a spacecraft into the orbit. SpaceX has made Falcon 9 reusable and believes this rocket is a needed breakthrough to reduce the cost of reaching space and to enable people to live on other planets.

Falcon 9 made history in 2012 when it delivered Dragon, a free-flying spacecraft designed to deliver both cargo and people to orbiting destinations, into the correct orbit for rendezvous with the International Space Station, making SpaceX the first commercial company ever to visit the station. Since then Falcon 9 has made frequent trips to space, delivering satellites to orbit as well as delivering and returning cargo from the space station for NASA. Falcon 9, along with the Dragon spacecraft, was designed from the outset to deliver humans into space and under an agreement with NASA, SpaceX is actively working toward this goal [3].
