In 2015, Toyota released 5,600 patents for free use until 2020, hoping to promote global development of hydrogen fuel-cell technology. Autonomous vehicles Toyota is regarded as being behind in smart car technology and in need of innovation. Although the company Toyota unveiled its first self-driving test vehicle in 2017, and has been developing its own self-driving technology named "Chauffeur" (intended for full self-driving) and "Guardian" (a driver assist system), neither of these has been introduced into any production vehicles. The company had set up a large research and development operation by 2018, spending almost US$4 billion to start an autonomous vehicle research institute in California's Silicon Valley and another ¥300 billion on a similar research institute in Tokyo that would partner with fellow Toyota Group companies and automotive suppliers Aisin Seiki and Denso. Toyota has also been collaborating with autonomous vehicle technology developers and, in some cases, purchasing the companies. Toyota has acquired the autonomous vehicle division of ride-hailing service Lyft for $550 million, invested a total of US$1 billion in competing ride-hailing service Uber's self-driving vehicle division, invested $400 million in autonomous vehicle technology company Pony.ai, and announced a partnership with Chinese electronics e-commerce company Cogobuy to build a "Smart Car Ecosystem." In December 2020, Toyota showcased the 20-passenger "e-Palette" shared autonomous vehicle, which was used at the 2021 Tokyo Olympic Games. Toyota has announced it intends to have the vehicle available for commercial applications before 2025. Since February 2021, Toyota has been building the sensor-laden "Woven City" which it calls a "175-acre high tech, sensor-laden metropolis" at the foot of Mount Fuji. When completed in 2024 the Woven City will be used to run tests on autonomous vehicles for deliveries, transport and mobile shops with the city's residents participating in the living laboratory experiment. Motorsports Toyota has been involved in many global motorsports series, providing vehicles, engines and other auto parts under both the Toyota and Lexus brands. Toyota Gazoo Racing (GR) is Toyota's performance brand that is used in many of the world's major motorsports contests. Toyota Gazoo Racing Europe, based in Cologne, Germany, competes in the FIA World Endurance Championship, while the Finland-based Toyota Gazoo Racing WRT participates in the World Rally
