> 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.
You clearly don't drive in a location that heavily salts roads! Here, a 15 year old car with 50,000 km is only marginally better than a 15 year old car with 200,000km - and it's mostly because the lower mileage car has probably been driven less in the winter.
Ultra-high mileage vehicles driven over short timeframes where rust doesn’t get a chance to set would probably get into wear-and-tear of structural welds. Something like how airframes are rated for x number of decompression cycles.
