The Beijing Technology Fair has been the scene in which this futuristic urban transport model has been presented, which aims to revolutionize everything related to the circulation of large cities.
It is qualified as a bus, although it is not on wheels. It runs on rails, and its main feature is that it literally passes over cars, which allows it to get around any traffic jam.
Its capacity also allows transporting about two thousand passengers.
