The history of self-driving cars

Once little more than a Hollywood-esque pipe dream, autonomous cars became a reality in the 2010s thanks largely to the research carried out by tech companies like Google. Although they haven’t merged into the mainstream yet and you can’t buy one as of writing, self-driving prototypes log millions of miles on our nation’s roads annually.

Compressing the history of self-driving cars into fewer than 10 milestones isn’t easy, but we’ve done our best.

The driverless dream begins

History of self-driving cars

It didn’t take long after the birth of the automobile for inventors to start thinking about autonomous vehicles. In 1925, inventor Francis Houdina demonstrated a radio-controlled car, which he drove through the streets of Manhattan without anyone at the steering wheel. According to a period New York Times report, the radio-controlled vehicle was able to start its engine, shift gears, and sound its horn “as if a phantom hand were at the wheel.”

As an amusing aside, Houdina’s name sounded sufficiently like that of the famous escape artist and illusionist Harry Houdini that a lot of people thought this was Houdini’s latest trick. Houdini visited the Houdina Company and got into a physical altercation, during which he broke an electric chandelier.

John McCarthy’s robo-chauffeur

In 1969, John McCarthy — who is celebrated as one of the founding fathers of artificial intelligence — described something similar to the modern autonomous vehicle in an essay titled “Computer-Controlled Cars.” McCarthy referred to an “automatic chauffeur” capable of navigating a public road via a “television camera input that uses the same visual input available to the human driver.”

He wrote that users should be able to enter a destination using a keyboard, which would then prompt the car to immediately drive them there. Additional commands would allow users to change the destination, stop at a restroom or restaurant, slow down, or speed up in the case of an emergency. No such vehicle was built, but McCarthy’s essay laid out the mission for other researchers to work toward.

No Hands Across America

Neural Network-Based Autonomous Driving

In the early 1990s, Carnegie Mellon researcher Dean Pomerleau wrote a Ph.D. thesis describing how neural networks could allow a self-driving vehicle to take in raw images from the road and output steering controls in real time. Pomerleau wasn’t the only researcher working on self-driving cars, but his use of neural nets proved way more efficient than alternative attempts to manually divide images into “road” and “non-road” categories.

In 1995, Pomerleau and fellow researcher Todd Jochem took their Navlab self-driving car system on the road. Their bare-bones autonomous minivan (they had to control speed and braking) traveled 2,797 miles coast-to-coast from Pittsburgh to San Diego in a journey the pair dubbed “No Hands Across America.”

The Grand Challenge is too challenging

 

DARPA announced its first Grand Challenge in 2002. It offered scientists from top research institutions a $1 million prize if they could build an autonomous vehicle able to navigate a 142-mile course through the Mojave Desert.

The challenge was held in 2004. None of the 15 participants was able to complete the course. The “winning” entry covered less than 8 miles in several hours before catching fire. It was a damaging blow to the goal of building real self-driving cars; after news of the fire made headlines, many assumed full autonomy was impossible to reach.

Parking gets smarter

While autonomous vehicles still looked like science fiction in the 2000s, self-parking systems began to emerge either as standard or optional equipment (and mostly on luxury cars). They demonstrated that sensors were close to being able to deal with relatively challenging real-world conditions, like parallel parking in a tight space.

Toyota’s hybrid Prius offered automatic parallel-parking assistance in 2003, while Lexus soon added a similar system to the LS, its flagship sedan. Ford launched Active Park Assist in 2009, and BMW followed a year later.

Google searches for an answer

Google secretly launched its Self-Driving Car Project in 2009. Known as Waymo in 2020, it was initially led by Sebastian Thrun, the former director of the Stanford Artificial Intelligence Laboratory and the co-inventor of Google Street View. It took a few years for the company to announce its prototypes had collectively driven 300,000 miles under computer control without a single accident, an impressive feat that caught many off-guard.

In 2014, it revealed an autonomous prototype without a steering wheel, a gas pedal, or a brake pedal; it was 100% autonomous. Waymo is widely hailed as the uncontested leader in self-driving technology.

The big car manufacturers dive in

By 2013, car companies including General Motors, Ford, Mercedes-Benz, and BMW were working on their own self-driving technologies. True autonomy proved more difficult to achieve than many assumed, both from a technical and a legal standpoint, and the technology available to consumers in the 2010s was partially automated at best.

The first autonomous car fatality

Claims that self-driving technology is safer than human drivers were called into question when one of Uber’s Volvo XC90-based prototypes hit and killed 49-year-old Elaine Herzberg as she crossed a street in Arizona. Although she was jaywalking, the crash was deemed entirely avoidable. Police officers concluded Uber’s safety driver (who is supposed to take over in the event of an emergency) was watching Hulu until half a second before the impact.

A.I. comes to self-driving cars

At CES 2018, Nvidia unveiled a new self-driving car chip, called Xavier, that incorporates artificial intelligence. The company then announced that it was partnering with Volkswagen to develop A.I. for future self-driving cars. While not the first effort to imbue autonomous cars with A.I. (Toyota was already researching the concept with MIT and Stanford), the Volkswagen-Nvidia collaboration is the first to connect A.I. to production-ready hardware. It opens up the possibility for self-driving cars to perform better, as well as for new convenience features like digital assistants.

What’s next?

In 2020, most automakers have cooled their self-driving car ambitions and taken a far more realistic approach to developing the technology. There is not a single autonomous car that members of the general public can buy, but some firms think they’re close to cracking the code. Billions of dollars and an enviable monopoly are at stake.

Tesla sells an option package named Full Self-Driving, but its cars aren’t autonomous by any means of measurement; the German government notably asked it to stop using this term. Volkswagen is developing the technology in-house, and it pledged to deploy retro autonomous vans during the 2022 World Cup. And German supplier Bosch joined forces with Mercedes-Benz parent company Daimler to put autonomous S-Class-based prototypes on the streets of San Jose. Other partnerships, projects, successes, and failures will undoubtedly emerge in the early 2020s.

Autonomy levels explained

While the terms “self-driving” and “autonomous” are thrown around a lot, not all vehicles have the same capabilities. The SAE autonomy scale is used to determine different levels of autonomous capability. Here’s a breakdown.

Level 0: No automation. The driver controls steering and speed (both acceleration and deceleration) at all times, with no assistance at all. This includes systems that only provide warnings to the driver without taking any action.

Level 1: Limited driver assistance. This includes systems that can control steering and acceleration/deceleration under specific circumstances, but not both at the same time.

Level 2: Driver-assist systems that control both steering and acceleration/deceleration. These systems shift some of the workload away from the human driver, but still require that person to be attentive at all times.

Level 3: Vehicles that can drive themselves in certain situations, such as in dense traffic on divided highways. Human intervention is not needed when autonomous mode is engaged, but the driver must be ready to take over when the vehicle encounters a situation that exceeds its limits.

Level 4: Vehicles that can drive themselves most of the time, but may need a human driver to take over in certain situations.

Level 5: Fully autonomous. Level 5 vehicles can drive themselves at all times, under all circumstances. They have no need for manual controls.

Tesla posts exaggerate self-driving capacity, safety regulators say
Beta of Tesla's FSD in a car.

The National Highway Traffic Safety Administration (NHTSA) is concerned that Tesla’s use of social media and its website makes false promises about the automaker’s full-self driving (FSD) software.
The warning dates back from May, but was made public in an email to Tesla released on November 8.
The NHTSA opened an investigation in October into 2.4 million Tesla vehicles equipped with the FSD software, following three reported collisions and a fatal crash. The investigation centers on FSD’s ability to perform in “relatively common” reduced visibility conditions, such as sun glare, fog, and airborne dust.
In these instances, it appears that “the driver may not be aware that he or she is responsible” to make appropriate operational selections, or “fully understand” the nuances of the system, NHTSA said.
Meanwhile, “Tesla’s X (Twitter) account has reposted or endorsed postings that exhibit disengaged driver behavior,” Gregory Magno, the NHTSA’s vehicle defects chief investigator, wrote to Tesla in an email.
The postings, which included reposted YouTube videos, may encourage viewers to see FSD-supervised as a “Robotaxi” instead of a partially automated, driver-assist system that requires “persistent attention and intermittent intervention by the driver,” Magno said.
In one of a number of Tesla posts on X, the social media platform owned by Tesla CEO Elon Musk, a driver was seen using FSD to reach a hospital while undergoing a heart attack. In another post, a driver said he had used FSD for a 50-minute ride home. Meanwhile, third-party comments on the posts promoted the advantages of using FSD while under the influence of alcohol or when tired, NHTSA said.
Tesla’s official website also promotes conflicting messaging on the capabilities of the FSD software, the regulator said.
NHTSA has requested that Tesla revisit its communications to ensure its messaging remains consistent with FSD’s approved instructions, namely that the software provides only a driver assist/support system requiring drivers to remain vigilant and maintain constant readiness to intervene in driving.
Tesla last month unveiled the Cybercab, an autonomous-driving EV with no steering wheel or pedals. The vehicle has been promoted as a robotaxi, a self-driving vehicle operated as part of a ride-paying service, such as the one already offered by Alphabet-owned Waymo.
But Tesla’s self-driving technology has remained under the scrutiny of regulators. FSD relies on multiple onboard cameras to feed machine-learning models that, in turn, help the car make decisions based on what it sees.
Meanwhile, Waymo’s technology relies on premapped roads, sensors, cameras, radar, and lidar (a laser-light radar), which might be very costly, but has met the approval of safety regulators.

It might seem that the autonomous driving trend is moving at full speed and on its own accord, especially if you live in California.Wayve, a UK startup that has received over $1 billion in funding, is now joining the crowded party by launching on-road testing of its AI learning system on the streets of San Francisco and the Bay Area.The announcement comes just weeks after Tesla unveiled its Robotaxi at the Warner Bros Studios in Burbank, California. It was also in San Francisco that an accident last year forced General Motors’ robotaxi service Cruise to stop its operations. And it’s mostly in California that Waymo, the only functioning robotaxi service in the U.S., first deployed its fleet of self-driving cars. As part of its move, Wayve opened a new office in Silicon Valley to support its U.S. expansion and AI development. Similarly to Tesla’s Full-Self Driving (FSD) software, the company says it’s using AI to provide automakers with a full range of driver assistance and automation features.“We are now testing our AI software in real-world environments across two continents,” said Alex Kendall, Wayve co-founder and CEO.The company has already conducted tests on UK roads since 2018. It received a huge boost earlier this year when it raised over $1 billion in a move led by Softbank and joined by Microsoft and Nvidia. In August, Uber also said it would invest to help the development of Wayve’s technology.Just like Tesla’s FSD, Wayve’s software provides an advanced driver assistance system that still requires driver supervision.Before driverless vehicles can legally hit the road, they must first pass strict safety tests.So far, Waymo’s technology, which relies on pre-mapped roads, sensors, cameras, radar, and lidar (a laser-light radar), is the only of its kind to have received the nod from U.S. regulators.
