Microtransport works against energy efficiency to the extent that empty vehicles are moving around unoccupied. On the other hand, if they achieve higher utilization, then that is offset to some degree by better utilization of the embodied energy required to manufacture the vehicle.

Further, if self driving vehicles are well coordinated, they could achieve higher utilization of roadways, which would require less land and less concrete and steel to carry the same volume of people. Also, they would potentially be able to operate with more optimal acceleration and breaking.
