Self-driving cars may upend transit before cities can build it

Austin approved a $7.1B light-rail in 2020, but components of the plan have already been cut. Simultaneously, Waymo launched a 200-car autonomous fleet across the city. Cities now face a choice: invest in decadeslong fixed infrastructure projects or embrace flexible, on-demand autonomous vehicles that can navigate anywhere.

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.

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

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.

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.

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.

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.

Today's cars use turbocharged hybrid engines and AI-assisted technologies

Honda and Yamaha have developed motorcycles with self-balancing systems

Honda's "Riding Assist Technology" was introduced in 2017 and maintains the motorcycle's stability by leaning away from the direction of the front wheel and adjusting the front fork's angle at low speeds. Yamaha's system uses actuators to achieve balance during stops and starts.

School buses are the safest vehicles on the road

Even without seat belts or airbags, the big yellow school bus transporting millions of students to school each day remains the safest vehicle on the road. A long history of tragic lessons led to today's highly tested school bus design, including the padded compartments created by school bus seats, multiple emergency exits, cross-view mirrors, and more.

Domino's Pizza's 30-minute guarantee was discontinued after a string of delivery-driver accidents

The chain's promotional gimmick offered customers free or reduced pizzas if their pizzas weren't delivered in 30 minutes or less. That policy led to the chain's popularity, but it also led to reckless driving: In the late '80s, the National Safe Workplace claimed its drivers had the same death rate as miners. After Domino's was found liable in 1993 for nearly $79M in damages, it discontinued the policy.

How medical robots could cure cancer

Medical robots are on the verge of being able to be injected into the body, where they will be responsible for semi-autonomous behavior, such as detecting cancer cells and distributing medication.
