The work is seen as essential to test and prove vehicle safety. The Government is also calling for views from industry and others ahead of a fuller policy proposal about the potential opportunities, obstacles and dangers entailed in likely transport developments, to help Britain get ahead of the competition. The initial aim is to explore regulatory barriers to technological and service innovation, and how data can be better used to improve transport, as well as the potential disadvantages of some technologies. The possibilities the Government envisages include not only increased use of drones which cities are already pioneering to help emergency services, but the possible introduction of aerial passenger vehicles.
