One scenario I’d like to suggest for consideration (and maybe you do in later posts) is the advent of self-driving vehicles. In this scenario, it could be favorable to not necessarily own a vehicle but for a fleet of vehicles to be available, Uber style, to provide transportation needs; a Transportation as a Service (TaaS) model. This would cut down on car ownership drastically, possibly alleviating the requirement for raw materials, increasing transportation efficiency (few/no traffic jams), and provides the incentive for maximum battery capacity (less downtime).
This scenario would require yearly aggregate spending to be less than the cost of maintenance, fuel, registration, insurance, etc. which is yet to be seen.
Certainly not a silver bullet and the timeline may not line up but it presents a possible piece of the solution puzzle.
