A drone taxi, or an "air taxi", completed its first test flight in an urban air mobility demonstration event on South Korea's southern Jeju Island on Wednesday, according to the Yonhap News Agency.

Developed by the Kencoa Aerospace Corporation, a South Korean drone maker, the "taxi" can accommodate one adult. It is an electrically powered vehicle that can travel up to 80 kilometers per hour, and transport up to 100 kilograms of cargo.

Jeju Island had planned to commercialize "air taxi" services in 2025, Business Korea said on September 15.

It said that a consortium consisting of three corporations had signed a Memorandum of Understanding with the Jeju Special Self-Governing Province, aiming to provide commercial urban air mobility service three years later.

The island was seen by the consortium as "an ideal test bed for air taxis" due to its "good airport facilities and well-maintained traffic infrastructure," according to a report in JoongAng Daily.

The country planned to develop and operate a mobility platform and a communication system on the island and built a vertical take-off and landing site.

The idea of an air taxi is not new, since countries like the United States, Germany, French, Italy and China have built their own air taxis, and some have planned to commercialize air taxis between 2024 and 2025.

Apart from taxis themselves, other infrastructures for the "flying cars" are also under construction. An airport for flying taxis was opened in April in an England car park, according to the Financial Times. It is "the first demonstration of a 'vertiport' for electric vertical take-off and landing aircraft, it said.

The BBC said in a previous report that flying cars may "change the world," but vehicles are required to be safe to fly, "road" should be legal, and the public is "willing to fly in them".
