It appears that the world (or at least some US states) is about to allow driverless cars onto its streets.
Today’s invention is to take that to another level by introducing riderless motorcycles.
These could be used in a number of roles. First, they might be employed to deliver packages quickly between offices, using much less fuel than a car and without creating traffic jams (bikes would probably be electric, gyro-stabilised and designed to prevent humans climbing aboard).
Second, they could be injected into motorway traffic streams and, by coordinating their speed adjustments via radio, help smooth out the waves of braking and acceleration which lead to tailbacks and collisions between human-driven vehicles.
