What is Tesla Autopilot and how does it work?

Don’t let the name Autopilot fool you: None of the cars in Tesla’s current range are capable of driving themselves. Instead, Autopilot is a partially automated system that is regularly improved via over-the-air software updates. It relies on eight surround-view cameras that give the car 360-degree visibility for up to 820 feet, 12 ultrasonic sensors, and a forward-facing radar. Tesla has regularly stressed that, unlike its rivals, it doesn’t believe in lidar technology.

The data gathered by Autopilot’s hardware allows the car to steer, accelerate, and brake automatically within its lane, commonly called adaptive cruise control, though the company warns the system requires active driver supervision. In other words, even if your Model S can steer itself around a bend, you shouldn’t be watching a movie while you cruise down I-80 at 75 mph. There are many circumstances Autopilot can’t handle on its own, and the driver could be asked to take over without notice.

Tesla also offers a more comprehensive suite of partially automated technology confusingly named Full Self-Driving Capability. We can’t stress this enough: It does not turn a Tesla into a self-driving car. Will it one day? Maybe. Hopefully, considering it’s a very expensive option. But, as of 2020, your new Tesla will be human-driven even if it’s equipped with Full Self-Driving. With that disclaimer out of the way, the suite adds Navigate on Autopilot (which suggests lane changes and tackles on- and off-ramps on its own), Smart Summon (which lets users move their car in and out of a parking spot), plus Traffic and Stop Sign Control (which recognizes and obeys traffic lights as well as stop signs). Note the latter feature is still in beta mode, so users are also the technology’s guinea pigs.

Owners have driven approximately 3 billion miles using Autopilot, according to Tesla. That’s far more than Cadillac owners have put on Super Cruise, but the system has been at the center of many high-profile (and sometimes deadly) crashes. Several government agencies (including the National Highway Traffic Safety Administration) have investigated its role in accidents, too. Its record is far from spotless.

Which cars have Tesla’s Autopilot?

Tesla makes Autopilot technology available across its entire range. It’s standard on the Model S, the Model X, the Model 3 (pictured), and the Model Y, and it will also be offered on the Cybertruck and the second-generation Roadster. It remains an independent company, and it’s not the sharing type, so there’s not a single non-Tesla-designed car offered with Autopilot. The company plans to keep its technology in-house in the foreseeable future.

Waymo’s Hyundai robotaxi deal may steal the show from Tesla
A Hyundai Ioniq 5 is equipped as a robotaxi.

Just days ahead of Tesla’s much anticipated robotaxi event on Thursday, Hyundai unveiled a partnership with Waymo that will add Hyundai’s Ioniq 5 to the fleet of the robotaxi operator.In the first phase of the partnership, Waymo will integrate its sixth-generation fully autonomous technology, called the Waymo Driver, into the all-electric Ioniq 5 SUV, which will be added to the Waymo One fleet over time.On-road testing with Waymo-enabled Ioniq 5s is due to start in late 2025 and become available to riders of the Waymo One robotaxi service the following year.Alphabet-owned Waymo currently operates the only functioning robotaxi service in the U.S., with a fleet of about 700 self-driving vehicles already on the road in Phoenix, Los Angeles and San Francisco. The service is also being tested in Austin, Texas.Last year, General Motors’ competing robotaxi service Cruise had to stop operations after one of its vehicles struck a pedestrian in San Francisco. Cruise’s GM vehicles are nonetheless expected to resume operations next year through a partnership with Uber.Driverless vehicles have stumbled on two main obstacles on the road to commercialization: The complexity of the technology and tight safety regulations.For now, Waymo’s existing footprint gives it a marked advantage over its competitors. Its sixth-generation technology is said to handle a wider array of weather conditions with fewer on-board cameras and sensors. In their joint statement, Waymo and Hyundai emphasized the proven safety of both the Waymo technology and the Ioniq 5. Waymo’s technology relies on pre-mapped roads, sensors, cameras, radar and lidar (a laser-light radar). It's an approach that might be very costly but has met the approval of safety regulators. All this adds pressure on Tesla to deliver the goods with the launch of its robotaxi -- expected to be called the Cybercab.Tesla’s ambition has been to eventually provide full driverless capacity directly to consumers. Tesla owners can already buy software called Full Self-Driving (FSD) that operates like an advanced driver assistance system and requires constant driver supervision.Tesla’s FSD relies on multiple onboard cameras to feed machine-learning models that, in turn, help the car make decisions based on what it sees.The technology, however, has not yet convinced all current and former traffic safety officials.

How to watch Tesla’s robotaxi unveiling on Thursday
Tesla's robotaxi event.

Tesla is holding a special event in California on Thursday that’s widely expected to focus on its highly anticipated robotaxi, dubbed the "Cybercab." It announced the event, called, "We, robot," in a post on X (formerly Twitter) on Wednesday.

The Tesla Supercharger network is expanding again

EV owners worried about getting stranded before their next charge may breathe a bit easier now: The Tesla Supercharger network has resumed its expansion over the last three months, after massive layoffs at Tesla had led to a slide in new stalls earlier this year.Tesla opened 2,800 new Supercharger stalls globally during the three-month period ending September 30, an increase of 23% from the year earlier, according to the company’s official Tesla Charging account on X (formerly Twitter).Tesla also delivered 1.4 terawatt hours (TWh) of energy during the third quarter, which translates to 27% year-over-year growth. The Tesla Charging account said the amount of energy delivered enabled Tesla owners to save over 150 million gallons of gasoline, offsetting more than 3 billion pounds of CO2.According to the website Supercharge.info, which relies on user contributions to track the opening of new stalls, there were 2,677 Supercharger stations in North America at the end of September, 125 more than at the end of the third quarter.The additions of new stalls, however, comes in the wake of a 31% slide in the second quarter, after a massive round of firings at the company removed 500 employees from the Supercharger team in April.The third-quarter expansion should still go some ways to appease the concerns of Tesla and non-Tesla electric vehicle (EV) owners, as EV manufacturers are lining up in droves to be able to use the Supercharger network.In September, General Motors electric vehicles made by Chevrolet, GMC and Cadillac joined the growing list of vehicles to have adopted Tesla’s North American Charging Standard (NACS). The network already allows access, via adapters, to EVs made by Ford, Rivian, Honda and Volvo. The likes of Nissan, Hyundai, Toyota, BMW, Volkswagen, Volvo and Jaguar have also signed agreements to start allowing access in 2025.
The Tesla map of Superchargers across the U.S. reveals they are concentrated in major cities and across East-West transit corridors.According to Tesla, a Supercharger can add up to 200 miles of range in 15 minutes.
