  • First Autonomous Ride Experience(0'001'58)
    Derek takes his first ride in a fully autonomous Waymo vehicle in a Phoenix, Arizona suburb. The car has no driver and operates entirely on its own.
    • Poll of YouTube viewers showed 50% are excited about autonomous vehicles • Over 40% believed the technology was still over 10 years away • Technology is currently functional under good road conditions
    The car demonstrates safe driving behavior by smoothly merging into traffic, waiting for oncoming cars before turning, and avoiding problems.
    Full disclosure that this video is sponsored by Waymo.
  • History of Autonomous Technology(1'585'15)
    Waymo started as the Google self-driving car project, beginning with the Firefly, a simple vehicle with no steering wheel or dashboard designed for public roads in October 2015.
    • Ridden by Steve Mann, who is legally blind • No steering wheel, no dashboard • No AC but has an emergency stop button • Super basic design with minimal features
    Before the 1940s, almost all elevators had drivers. When driverless elevators were introduced, the public was very resistant. An elevator drivers strike in New York City helped adoption of automated elevators. Today, finding a driver in an elevator would seem unusual.
    Airplanes are extensively flown by computers. CAT II autoland procedures allow planes to land themselves in heavy fog. In 2013, manual intervention led to the Asiana Airlines crash, demonstrating that computers are often safer in difficult conditions than human pilots.
  • Levels of Autonomy and Safety Concerns(5'159'07)
    There are different levels of autonomy, with levels up to four still requiring a human driver to remain responsible and keep their hands on the wheel.
    • Google employees testing early autonomous vehicles were observed rummaging through bags • Drivers were seen checking phones, putting on makeup, or even sleeping • Drivers were trusting the technology too much despite being told they were responsible
    Waymo decided the only safe way to proceed is with fully autonomous vehicles at level four autonomy, where no human driver is required or present.
    Waymo operates a depot with fleet dispatchers, rider support teams, and monitoring systems to ensure all missions are assigned daily and completed successfully on the road.
  • Sensor Technology and Perception(9'0711'38)
    • 360-degree LiDAR on top can see 300 meters away • 29 cameras provide full 360 vision with close and long range capabilities • Can detect a stop sign or pedestrian 500 meters away • Microphone listens for sirens to pull over for emergency vehicles
    LiDAR shoots invisible laser beams that scan millions of times per second, detecting reflections to determine distance. This paints a 3D picture of the world around the car.
    The vehicle constantly predicts where pedestrians and other road users are likely to go, imagining multiple possible futures and weighing the likelihood of each option.
    The car handled a sudden stop when detecting a person with a cart on a pedestrian crosswalk, demonstrating its ability to respond to unpredictable situations in parking lots.
  • Safety Data and Moral Questions(11'3813'02)
    Years ago, people debated who autonomous cars should hit in accidents (orphan vs nun, motorcyclist with/without helmet), but this misses the reality: 99% of accidents don't involve such dilemmas.
    • Around 1.3 million people killed yearly on roads due to human error • 60 million killed in 20th century—equivalent to a world war • National Transportation and Safety Board identifies human error as cause of 94% of accidents • Up to 200 people killed annually in US from backup incidents
    Most human errors are impossible for machines to make: speeding, driving under the influence, and distracted driving. Backup blind spots cause deaths that autonomous vehicles with 360 vision cannot.
    If autonomous cars reduce fatalities, the real moral dilemma is not having them on roads sooner rather than fearing they won't handle unlikely hypothetical scenarios.
  • Safety Performance and Evidence(13'0215'26)
    Waymo vehicles have accumulated 20 million miles of driving on public roads. An average human driver would need to drive for a thousand years to accumulate this experience.
    • Studied 6.1 million miles of automated driving in Phoenix metropolitan area • 18 total accidents occurred, none serious enough to expect significant injury or death • Types of accidents completely eliminated: going off road, hitting stationary objects
    Of eight significant accidents over six million miles, all eight involved human drivers doing something stupid: driving on wrong side, running red lights, failing to yield, or speeding 20+ mph over limit.
    Three incidents involving Waymo vehicles and pedestrians: in all three cases, the Waymo vehicle was stationary and the pedestrian or cyclist/skateboarder ran into the vehicle.
  • Training Through Simulation(15'2616'01)
    Waymo takes real-world data from actual driving and puts it into simulations, adjusting parameters like bicyclist speed, car turning speed, and other variables.
    The software has been trained on an additional 20 billion miles of driving in simulation, providing a thousand times more experience than the real-world 20 million miles.
    By tweaking scenarios in simulation, Waymo tests what the software will do under various conditions without risking public safety on roads.
    Waymo would never launch a rider-only service without meeting a base safety framework confirming the vehicles are safer than average human drivers.
  • Public Acceptance and Future Outlook(16'0117'57)
    After witnessing confident handling of parked cars, cyclists, and pedestrians, Derek stopped thinking about the car being autonomous. It takes about two minutes to forget you're in a driverless vehicle once you feel safe.
    • Riders with disabilities, seniors, and the blind can get around more easily • Transportation will become cheaper • Recovery of time spent in traffic, improving happiness • Reduction of traffic through better vehicle awareness
    When all cars are fully autonomous, they can execute coordinated driving like a beautiful ballet. This allows elimination of parking lots and addition of green spaces to cities.
    • Widespread adoption could prevent tens of thousands of fatalities in the US alone • Expected significant changes in big cities within the next five years • Waymo needs to drive sufficient miles to demonstrate safety to regulators
