They are a small part of the push to eventually make us all passengers rather than drivers. It’s about slowly taking the individual decisions out of transport, until all transport is effectively a component in a managed mass transit scheme.

If your schedule and destination are approved, the vehicle will follow an assigned route to the permitted destination. Enjoy the luxury, comrade.”
