Robotaxi, known as autonomous taxi, is a type of autonomous vehicle operated for ride-sharing companies. Robotaxis may significantly improve pollution and energy consumption because electric vehicles are heavily used in these projects, and in most cases, they require a smaller vehicle size and range compared to the usual individual owned vehicles.

Ride-sharing means the expectable reduction in the number of vehicles, thereby reducing embodied energy and traffic congestion. A significant portion of the operating costs of such services come from human drivers, so eliminating the need for human drivers is a very affordable solution for customers.
