I certainly hope I don't live to see this as it would require a combination of severe economic collapse and an authoritarian government to make this happen. And that's certainly not something I'd care to experience.

Sure, much driving is unnecessary. A great deal of the activities human beings engage in is unnecessary. The level of housing many enjoy in the US is certainly unnecessary. For that matter the expenditure of resources that allow us to waste our time tapping out our opinions on laptops is hardly necessary. But few people are going to give up driving or anything else they wish to do simply because they realize it's unnecessary.
