Waymo's perception system uses a combination of cameras, LiDARs, and RADARs. This setup allows for a 360-degree view of the surroundings.

Each LiDAR provides a point cloud showing the shape of obstacles, eliminating the problem of reflections. This technology is especially useful in complex traffic scenarios.

The system can detect and identify specific objects, such as cars, and even recognize visual cues like sirens and lights. This information is then used to inform the vehicle's behavior.

Waymo's mapping technology plays a crucial role in solving problems like detecting a person carrying a STOP sign. By matching the detected sign with the map and prior knowledge, the system can accurately determine the need to stop.

The goal of Waymo's machine learning models is to accurately estimate a 3D world. This is achieved by processing vast amounts of data from various sensors.

The system's ability to detect objects up to 300 meters away, thanks to LiDAR, is a significant advantage in complex driving scenarios.

Prediction is a crucial aspect of Waymo's self-driving technology. It's what allows the system to anticipate human behavior and make decisions accordingly.

To make these predictions, Waymo uses recurrent neural networks, which analyze past information to forecast future actions. This approach enables the system to understand and respond to complex situations.

One key aspect of Waymo's prediction system is its ability to incorporate expert bias. This means that human knowledge and experience are fed into the models to improve their accuracy and decision-making.

For example, if a pedestrian is seen running without looking, the risk of an accident increases. Waymo's system takes this into account and adjusts its predictions accordingly. This is made possible by the combination of machine learning and human knowledge of the world.

Waymo's prediction system is a hybrid approach that leverages both machine learning and human expertise. This allows the system to learn from data and also benefit from the knowledge and experience of human experts.

Crashes have been a concern for autonomous vehicles, with Waymo's 150 crashes reported by the NHTSA by July 2021, and Google's 14 minor collisions involving its self-driving cars by July 2015.

Most of these crashes did not result in injuries, but some did, like the incident in May 2023 where a Waymo robotaxi killed a dog in San Francisco while in "autonomous mode."

Waymo regularly publishes safety reports and claims to be nearly twice as safe as a human driver, with only 3 crashes with injuries over 7.1 million miles driven in 2023.

In February 2024, a driverless Waymo robotaxi struck a cyclist in San Francisco, highlighting the ongoing challenges of autonomous vehicles.

Waymo issued recalls for 444 of its vehicles after two hit the same truck being towed on a highway, demonstrating the importance of vehicle safety and recall protocols.

Waymo is burning through cash at an alarming rate. It has posted a $4.4 billion loss over the last fiscal year.

The cost base is high, mainly due to owning the vehicles it operates, unlike ride hailing players like Uber. This means Waymo incurs costs tied to vehicle retrofitting, mapping, and fleet management.

Waymo still loses money on every ride it delivers, which has meant that it's dependent on external funding. It has raised over $10 billion in funding since its inception.

The recent $5.6 billion Series C funding, led by Alphabet, has been a lifeline for Waymo. However, this reliance on external funding is a concern for the company's long-term viability.

Waymo LLC v. Uber Technologies, Inc. et al was a major controversy in the self-driving car industry.

In February 2017, Waymo sued Uber and its subsidiary Otto, alleging trade secret theft and patent infringement.

The company claimed that three ex-Google employees, including Anthony Levandowski, had stolen trade secrets, including thousands of files, from Google before joining Uber.

Levandowski allegedly downloaded 9 gigabytes of data that included over a hundred trade secrets; eight of which were at stake during the trial.

An ensuing settlement gave Waymo 0.34% of Uber stock, the equivalent of $245 million.

Uber agreed not to infringe Waymo's intellectual property.

Part of the agreement included a guarantee that "Waymo confidential information is not being incorporated in Uber Advanced Technologies Group hardware and software."

In statements released after the settlement, Uber maintained that it received no trade secrets.

Uber fired Levandowski in May, which resulted in the loss of roughly $250 million of his equity in Uber, almost exactly equating the settlement.

Uber halted production of self-driving trucks through Otto in July 2018 and shuttered the subsidiary company.

The DOJ's antitrust lawsuit against Alphabet could result in a breakup of Alphabet's portfolio, which would likely impact Waymo's growth.

Waymo's growth is accelerating, but it's a loss-making business that benefits from Google's capital, shared intelligence, and analytics.

The DOJ might be focusing on how Alphabet's organizational structure helps it cement its overall dominance, putting units like Waymo directly in regulators' sights.

Waymo depends on Alphabet for funding, technical resources, cloud computing, AI talent, and mapping data, which it would struggle to replicate without Alphabet's backing.

Without Alphabet's support, Waymo could face pressure to cut costs, which would be a bad time given Tesla's plans to ramp up deployments of its own robo-taxis.

Tesla has a massive installed base of vehicles on the road and plans to allow owners to rent out their vehicles to its robo-taxi fleet, which could give it better unit economics than Waymo.

If Waymo is forced to separate from Google, it risks losing its hard-won lead in the self-driving market.
