> If a car that costs $25,000 to manufacture all of a sudden can be driven 40-50 hours a week automatically, how much is that car now worth?
Cars depreciate based on distance driven, not on age. A car will need to be serviced every X miles and replaced every Y miles, and these numbers are independent of whether the car is driven one hour a week or forty. In no universe does driving more hours per week increase the value of a car.
