one of the reasons why acubed vahana was being developed as a self-steering aircraft was because the developers expected such a big volume of flights for which the current number of pilots would not be sufficient. another reason was the higher payload and saving on labour expenses. in contrast to autonomous driving, autonomous flying has to be navigated at a significantly higher speed and in three instead of two dimensions. this requires higher computing speed and faster sensors and actuators. the lidar system, together with cameras and radar helped to navigate autonomously.
