As of 2025, self-driving cars continue to be unavailable to consumers

Self-driving vehicles have the potential to cut ride costs by 40-50% and eliminate thousands of road deaths

Author Andrew Miller argues that widespread adoption of self-driving vehicles is no longer a distant promise, as Waymo expands into over 15 cities. However, he warns the technology's biggest remaining hurdles are political: liability, labor, and whether cities embrace or resist the shift.

In a 2024 survey, 93% of participants expressed concerns about self-driving cars

Safety was the leading consumer fear, with technological malfunctions coming in second. Nearly half of all consumers identified skepticism or concern as their primary descriptor for autonomous cars, but 20% cited enhanced mobility for the elderly and people with disabilities as a key benefit.

As of 2025, Waymo has rolled out "robotaxi" services in five US cities

The company has been under investigation by the National Highway Traffic Safety Administration following dozens of crashes and incidents that appear to show Waymo vehicles violating traffic laws over the past decade in Phoenix, San Francisco, Los Angeles, Atlanta, and Austin.

There is no clear national standard of laws for autonomous vehicle

Some US states allow self-driving vehicles to operate without a human driver present, while others require a licensed driver to be behind the wheel. As of January 2023, a total of 21 states have legalized autonomous vehicles in public, with six focused solely on semi-trucks.

In 2023, self-driving cars drove 3.3 million miles on California's roads

According to the state's DMV, the mileage represented a fivefold increase from the previous year. General Motors' Cruise and Alphabet's Waymo accounted for the bulk of miles, though 38 companies have received permits to test autonomous vehicles in the state.

The Society of Automotive Engineers sorts self-driving technology into six levels

At level 0, a vehicle cannot intervene on its own, and the driver controls all navigation. At level 3, the car operates autonomously under limited conditions, but a human can still take control. A future level 5 vehicle drives itself and lacks a steering wheel or pedals.

A suite of cutting-edge hardware and computation-intensive software creates the potential for self-driving cars to be safer, more fuel-efficient, and more accessible to a broader range of drivers. However, automation also introduces potential cybersecurity threats.

Future self-driving cars may communicate across a closed wireless infrastructure

Current autonomous vehicles collect and analyze their own data through their own hardware and proprietary software. Connecting data from all such cars on a single network will require overcoming challenges related to standardization and security.

Self-driving car companies like Waymo use lidar technology for navigation

By firing thousands of laser pulses in all directions, lidar systems construct 3D maps of a car’s surroundings, even in environments with limited lighting. The technology has also been incorporated into iPhones and the Vision Pro headset to improve camera focus.

Nearly every major automaker now offers a hands-free driving system

The capabilities of these systems range from automatic lane changes via eye-tracking to an assistant that reminds you to check your blind spot before changing lanes yourself. Most systems still require the driver to remain alert and be prepared to take over.

As of 2025, artificial intelligence systems remain narrow and specialized

Efforts are ongoing to create artificial general intelligence, where machines outperform humans across a wide range of cognitive tasks, including those for which they have not been specifically trained. Current models utilize machine learning and neural networks to perform tasks for which they are programmed, leveraging provided training data.

As of 2025, there are no federal laws involving privacy and smart city technologies

Advancements in cloud technology and artificial intelligence allow cities to capture, store, and analyze more information than ever before. Experts warn that the unhindered ability to collect and use this data may infringe on residents' rights and endanger them if the data gets into the hands of malicious parties.
