Smart cars are for stupid drivers.
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. I can see the not too distant future now: “Before exercising the privilege of movement you must first file an electronic travel application and let the vehicle submit it for approval. If your schedule and destination are approved, the vehicle will follow an assigned route to the permitted destination. Enjoy the luxury, comrade.”
