Robotaxi
Overview
A Robotaxi refers to an unmanned taxi service that transports passengers to their desired destination using only autonomous driving technology, without a driver. It is based on Level 4 or higher autonomous driving technology, and the entire process—including vehicle hailing, route optimization, and fare payment—is automated. Robotaxis are gaining attention as a key innovation in transportation, with the potential to transform urban traffic systems and the mobility industry paradigm.

Technological Foundation
Robotaxis rely on three core technologies. First, sensor fusion. Various sensors such as LiDAR, radar, cameras, and ultrasonic sensors recognize the surrounding environment in 360 degrees. Second, artificial intelligence (AI) algorithms. Deep learning-based object recognition, path planning, and control algorithms make real-time driving decisions. Third, high-definition maps (HD Maps) and V2X (Vehicle-to-Everything) communication. Road lane, traffic light, and sign information is pre-stored, and communication between infrastructure and vehicles enhances predictive capabilities.
Major Players and Service Status
- Waymo: A subsidiary of Alphabet (Google), operating commercial robotaxi services in Phoenix, San Francisco, and Los Angeles, USA. As of 2024, it records over 100,000 paid trips per week, leading the industry.
- Cruise: An autonomous driving company acquired by GM, which launched services in San Francisco but suspended operations after a 2023 accident due to regulatory measures. As of 2025, it is preparing to resume.
- Tesla: Elon Musk unveiled the robotaxi concept 'Cybercab' at the 'We, Robot' event in October 2024. Mass production is targeted for 2026, but Level 4 certification has not yet been obtained.
- Chinese Companies: Baidu's 'Apollo Go' operates in 10 cities including Beijing, Wuhan, and Chongqing, surpassing 100 million km in cumulative driving distance by the end of 2024. Pony.ai and WeRide have also received commercial permits.
- Domestic Status (South Korea): Hyundai Motor began a pilot robotaxi service based on the Ioniq 5 in Las Vegas, USA in 2024, and has been conducting demonstration projects on Jeju Island and parts of Seoul since 2025.
Regulation and Safety
The biggest obstacles to robotaxi commercialization are regulation and safety. In the USA, regulations vary by state rather than federal guidelines, with the California Public Utilities Commission (CPUC) handling permits. Regulations were tightened after the 2023 Cruise accident. In South Korea, the Ministry of Land, Infrastructure and Transport implemented the 'Act on Promotion and Support for Commercialization of Autonomous Vehicles' in 2024, clarifying temporary operation permits and accident liability rules. In terms of safety, remote monitoring systems and immediate response protocols for accidents are essential.
Economic and Social Impact
Robotaxis can reduce operating costs by 30–50% by eliminating driver labor costs, expected to provide mobility services cheaper than private car ownership. However, issues such as job losses for existing transportation workers (e.g., taxi drivers, chauffeurs), data privacy, and cybersecurity threats are also raised. Additionally, there are positive effects of expanding mobility rights for transportation-disadvantaged groups (e.g., elderly, disabled).
Latest Trends
In 2024–2025, the robotaxi industry is moving along two axes: 'expansion of commercialization' and 'strengthening safety.' Waymo launched services in Miami in January 2025 and integrated robotaxis into the Uber ride-hailing platform through collaboration. China expanded dedicated robotaxi zones in Beijing in 2025 and launched airport-to-city center routes at Shanghai Pudong International Airport. Tesla unveiled a Cybercab prototype in June 2025, reaffirming its 2026 production schedule. Meanwhile, the US National Highway Traffic Safety Administration (NHTSA) issued a mandatory robotaxi accident reporting regulation in March 2025, and the European Union (EU) plans to establish an 'Autonomous Vehicle Liability Directive' by the end of 2025. Domestically (South Korea), robotaxi pilot services expanded to the general public in Seoul's Sangam and Pangyo areas in July 2025, and Hyundai Motor plans to begin production of robotaxi-dedicated vehicles at its Metaplant in Georgia, USA in the second half of 2025.
