I thought that intuitively at first, but uneducated napkin math seems to disagree. Say a Cab costs $50k upfront plus $.5 times 200,000 miles gives us $150,000

I thought that intuitively at first, but uneducated napkin math seems to disagree. Say a Cab costs $50k upfront plus $.5 times 200,000 miles gives us $150,000 for the vehicle over it's lifetime. If hiring, insuring, managing, and paying a driver costs 100k per year and it takes say 5 driver years for that car to reach EOL, you're at 500k for the driver. Perhaps someone with a better knowledge of the numbers could chime in, but if I'm reasonably close, that driver is a big chunk of costs.
