  • More companies are trying to bring self-driving cars to the masses than

  • ever before. Yet a truly autonomous vehicle still doesn't exist.

  • And it's not clear if, or when, our driverless future will arrive.

  • Proponents like Elon Musk have touted an aggressive timeline but missed

  • their goals and others in the industry have also missed projections.

  • Well, our goal is to deploy these vehicles in 2019.

  • So you'll have the option to not drive.

  • It's not happening in 2020.

  • It's happening today. We wanted to check in.

  • Where exactly are we with self-driving cars?

  • And when can we expect them to be part of our daily lives?

  • The current state of driverless cars is very interesting because we've

  • passed what people refer to as peak hype and we've entered what's called

  • the trough of disillusionment.

  • Which is, even people within the industry are saying, gee, it turns out

  • there's a lot harder than we thought.

  • We're definitely not anywhere near as far along as a lot of people thought

  • we would be three years ago.

  • But I think over the last 18 to 24 months, there's been a real injection

  • of reality. There was a sense maybe a year or two ago that our algorithms

  • are so good, we're ready to launch, we're gonna launch driverless cars any

  • minute. And then obviously there's been these setbacks of people getting

  • killed or accidents happening and now we're a lot more cautious.

  • Several big players have begun to walk back their predictions on how soon

  • we could see this technology.

  • Even Waymo's Chief External Officer admitted that the hype around its

  • self-driving cars has become unmanageable.

  • The technology has come a long way, but there's still a lot of work to be

  • done. There's the perception, which is, using the sensors to figure out

  • what's around the vehicle, in the environment around the vehicle.

  • Prediction, figuring out what those road users are going to be doing next

  • in the next few seconds.

  • Turns out the perception and especially prediction are really, really hard

  • problems to solve. Companies tackling self-driving today are taking two

  • general approaches. Some are building a self-driving car from the ground

  • up. Others are developing the brains that drive the car.

  • An early leader was Google, who started its self-driving car project in

  • 2009. Known as Waymo today, the company is developing hardware and

  • software that can function as the brains in a self-driving car.

  • Aurora is taking a similar approach.

  • Founded in 2017 by early players from Uber, Tesla and Google's

  • self-driving initiatives, it's already raised $620 million in funding from

  • Amazon and other big name investors.

  • Aurora is testing vehicles on the road in Pittsburgh, Pennsylvania and out

  • here in the Bay Area. We don't yet let the public in our cars.

  • Our cars are on the road, we have two of our test operators in there.

  • The technology we're building can operate from a compact electric car, to

  • a minivan, to even a big, long haul truck.

  • Argo AI and Aptiv are examples of other companies taking a similar

  • approach. Lyft is developing its own self-driving systems now too and

  • offering self-driving rides on its app through partnerships in select

  • areas. Self-driving is too big for just one company and one effort.

  • And if you look at our strategy, that is why we're working with partners

  • on the open platform, Aptiv and Waymo, and why we're building the tech

  • here. Companies like Tesla, Zoox and GM, with its Cruise division, are

  • making their own vehicles.

  • Aiming for self-driving cars that can operate in all environments.

  • This is the engineering challenge of our generation.

  • We've raised seven and a quarter billion dollars of capital.

  • We have deep integration with both General Motors and Honda, which we

  • think is central when you're building mission critical safety systems and

  • building those in a way that you can deploy them at very large scale.

  • Cruise, which was acquired by General Motors in 2016, has been testing its

  • fleet of vehicles in San Francisco with safety drivers onboard.

  • To give you a sense for the magnitude of the difference between suburban

  • driving and what we're doing everyday on the streets of San Francisco.

  • Our cars on average see more activity in one minute of San Francisco

  • driving than they see in one hour of driving in Arizona.

  • Zoox, led by the former chief strategy officer at Intel, is working on

  • creating an all in one self-driving taxi system with plans to launch in

  • 2020. Instead of retrofitting cars with sensors and computers and saying,

  • hey, here's a self-driving car.

  • We think there's an opportunity to create a new type of vehicle that from

  • the very beginning was designed to move people around autonomously.

  • Nissan and Tesla both have semi-autonomous systems on the roads today.

  • Tesla's has been available in beta on its vehicles since 2015 and drivers

  • have been known to use the current system hands-free.

  • Tesla's promising full self-driving software is just around the corner.

  • It's going to be tight, but it still does appear that we'll be at least in

  • limited, in early access release, of a feature complete full self-driving

  • feature this year. I think Tesla is actually a lot further back than they

  • would like the world to to believe they are because they are, in fact, so

  • much more limited in terms of their hardware.

  • Others are making self-driving shuttles that operate along designated

  • routes only or focusing on trucks with long haul highway routes.

  • And then there are companies like Ghost and Comma.ai

  • working on aftermarket kits.

  • Essentially hardware that could be installed in older cars to bring them

  • new self-driving capabilities one day.

  • For all players in this space, the path ahead is filled with challenges.

  • Chief among them, proving the technology is safe.

  • Driverless systems have to meet a very high safety bar that has to be

  • better than a human before they're deployed at scale.

  • There are no federally established standards or testing protocols for

  • automated driving systems in the U.S.

  • today, but there have been fatal crashes.

  • A woman named Elaine Herzberg was killed by an autonomous Uber with a

  • safety driver who was paying no attention.

  • This woman was crossing the street, walking her bicycle, should easily

  • have been seen by the autonomous vehicle, was not, was run over.

  • Nobody stepped on the brakes.

  • In 2016, a Tesla fan named Joshua Brown died in a crash while using

  • autopilot hands-free in Florida.

  • Other autopilot involved accidents are now under investigation.

  • Still, the industry is hopeful that autonomous vehicles will make the

  • roads far safer than they are today.

  • Really, the kind of zero to one moment for the industry will be when we

  • can remove those safety drivers safely and the vehicle can operate without

  • the presence of any human. Others, like Elon Musk, have said it's almost

  • irresponsible not to have these vehicles out there because they are safer

  • and will be safer than human drivers.

  • Even if we could say that an autonomous vehicle was better than a human

  • driver, it doesn't mean that an autonomous vehicle is better than a human

  • driver plus all of the advanced driver assist systems we have.

  • When looking at when the tech could actually be ready one of the principle

  • metrics touted by companies is the number of miles driven, but not all

  • miles are created equal when testing automated systems.

  • You could take an autonomous vehicle and go, put it on an oval track or

  • just a straight road, and you could drive 100 million miles.

  • But that's not really gonna tell you much about how well the system

  • actually functions because it's not encountering the kinds of things that

  • are actually challenging in a driving environment.

  • Testing self-driving vehicles out on public roads isn't enough.

  • They need to be exposed to every imaginable scenario, so companies rely on

  • simulation. We can create situations that we're basically never going to

  • see or very rarely see.

  • So, for example, we might want to simulate what happens as a bicycle comes

  • through an intersection, runs a red light and crashes into the side of our

  • car. Turns out that doesn't happen very often in the real world, but we

  • want to know that if that happens, our vehicles are going to do something

  • safe. Basically allow the car to practice up in the cloud instead of on

  • the road. When you're testing autonomous vehicles out on public roads, not

  • only are the people riding in that car part of the experiment, but so is

  • everybody else around you. And they didn't consent to being part of an

  • experiment. I remain concerned that humans will be used as test dummies.

  • Instead of self-certification and de-regulation I want to see strong

  • independent safety regulations from the agencies in front of us today.

  • The self-certification approach did not work out well for the Boeing 737

  • Max 8 and now Boeing is paying the price.

  • We should heed that lesson when it comes to finding out the best way to

  • deploy autonomous vehicles.

  • Lawmakers held hearings this month to figure out how to keep the public

  • safe without holding back self-driving innovation.

  • In September, the National Highway Traffic Safety Administration released

  • new federal guidelines for automated driving systems.

  • But they're only voluntary suggestions at this point.

  • State legislation is farther along.

  • As of October, 41 states have either enacted laws or signed executive

  • orders regulating autonomous vehicles.

  • With regulatory questions looming, it's no surprise that self-driving

  • companies are proceeding cautiously at first.

  • What we're going to be seeing in the next several years is more limited

  • deployments in very specific areas where there's confidence that the

  • technology can work. I think we'll see limited deployments of self-driving

  • vehicles in the next five years or so.

  • You'll see these moving goods and you'll see them moving people, but

  • you'll see them specifically in fleet applications.

  • Aurora says its systems could be integrated into any vehicle, from fleets

  • of taxis to long haul trucks.

  • The cost of self-driving technology is another deciding factor for how it

  • will be deployed. Most consumers are never going to own a vehicle that's

  • really autonomous because the technology is expensive and there's a whole

  • raft of issues around product liability and making sure that it's properly

  • maintained and sensors are calibrated.

  • That's one reason ride hailing companies Lyft and Uber are getting in the

  • game. We have two autonomous initiative.

  • One is the open platform where we're connecting Lyft passengers with our

  • partner self-driving vehicles.

  • And so this is Aptiv in Las Vegas and Waymo in Chandler, Arizona.

  • And then also kind of the product experience for the tech that you see

  • here, which is Level 5. As AV companies inch toward the mainstream public

  • perception, simple understanding of the tech has become another issue that

  • could impact progress.

  • Some in particular in the industry have done a disservice to the public in

  • overhyping the technology before it's really ready.

  • It's still not very clear to most people what we mean when we say

  • driverless car. Waymo and General Motors Cruise Automation are very

  • close to having what they referred to as level five cars most of the time.

  • In other words, again, they can in theory function all by themselves.

  • But so far, it seems that they function like a 15 year old driver hoping

  • to get a driver's license.

  • There's a lot of people who think that you can buy autonomous vehicles

  • today, especially when you can go out and buy a car, buy an option that's

  • called full self-driving and pay for that.

  • You expect that it actually exists.

  • And the fact is, it does not exist today.

  • With an uncertain timeline and a history of missed targets, public

  • confusion is no surprise.

  • Despite big developments, most companies have recognized we are still

  • years away from having truly self-driving cars as part of our daily lives.

  • One big question is when is the car ready?

  • You have to have a good sense of all of the scenarios and all of the

  • situations that the vehicle will need to encounter.

  • And that just takes time.

  • We expect level four vehicles to be feasible in small quantities within

  • the next five years.

  • And what that means is you'll probably see hundreds or maybe thousands of

  • vehicles out either delivering packages or moving people through

  • neighborhood or maybe hauling goods on our freeways.

  • And now, even the experts hesitate to make promises on when true

  • self-driving will get here.

  • You always have to assume that the user is going to find a way to misuse

  • the technology. Assume the worst and then design for that.

  • I think it's a mistake to be over promoting the technology, over hyping it

  • when it's still very much a work in progress.

  • This is something we need to do with society, with the community and not

  • at society. And we take that very seriously.

  • We're building mission critical safety systems that are going to have a

  • huge positive impact on people's lives.

  • And the tech adage of move fast and break things most assuredly does not

  • apply to what we're doing here.
